2.3 Electrical Installation
Before installation ensure that all incoming power sources are turned off. Failure to
observe this practice can result in serious or even fatal injury and damage to equipment.

Connections to the PMU PRO are made via front terminals as shown in Figure 2-5.

Please pay attention to the following notes before installation:

· Under no circumstances should the instrument be connected to a power source if it is damaged.

· Before connecting the instrument to the power source, check the labels on the front and side of the instrument to ensure that your instrument is equipped with the appropriate power supply, voltage inputs and current inputs.

· The secondary of an external current transformer must never be allowed to be open circuit when the primary is energized. An open circuit can cause high voltages, possibly resulting in equipment damage, fire and even serious or fatal injury. Ensure that the current transformer wiring is secured using an external strain relief to reduce mechanical strain on the screw terminals, if necessary.

· When mounting the instrument on a DIN rail inside a switchgear, the metal plate of the switchgear must be grounded for safety purposes.

· Use a 2A low-voltage circuit breaker before connecting the voltage inputs to mains.

· Use non-insulated ferrules, such as Panduit Pan-Term® F77-8-M termination.

for wire

· Provide adequate segregation or barrier separation between the different classes of circuits: (a) Class 1 field and factory wiring (CT output leads, voltage measurement leads, mains input power), terminals, and bare live parts, and (b) Class 2 and Class 3 field and factory wiring, terminals, and non-insulated live parts.

Clock and Time Synchronization

3.4 Clock and Time Synchronization
Time synchronization provides a common time basis for synchrophasor measurements and data recorders.
The PMU PRO clock must be synchronized to UTC time using an external IRIG-B timecode source or from an IEEE 1588 PTPv2 master clock.
You can see the clock status in the status bar on the front display and check the time quality on the Monitor/Clock Status screen (see “Device Clock Status” in 4.3.3).
You can also check the clock status and time accuracy via Telnet using the “time” command as shown in the following picture.

3.4.1 IRIG-B Time Synchronization
To enable the IRIG-B port as a UTC source, select the IRIG-B time synchronization option in the device Local Settings setup.
The IRIG-B port uses an unmodulated (pulse-width coded) timecode signal (unbalanced 5V level) according to the IRIG 200-04 standard. It supports B004/B005 timecode formats with time code extensions specified for the IRIG-B profile in Annex D of IEEE Std C37.118.1-2011.
The IRIG-B port can synchronize to the IRIG-B timecode source with sub-microsecond accuracy.
3.4.2 IEEE 1588 PTP Time Synchronization
The Ethernet port must be connected to an IEEE 1588 grandmaster clock through a 1588 PTPv2 peer-to-peer transparent clock switch compliant with IEEE Std 1588-2008 and IEEE C37.238 power profile.
To enable 1588 Ethernet ports as a UTC source, select the IEEE 1588/PTP time synchronization option in the device Local Settings setup.
Both Ethernet ports can be connected to the same or two different 1588 switches. The device will obtain UTC time from one of the available sources and automatically switch to the other port whenever the signal is lost for any reason.
Each port implements an ordinary PTPv2 slave clock, complying with the IEEE C37.238 power profile:

PMU PRO Phasor Measurement Unit

3 Operating the PMU PRO

Synchrophasor Measurements

· PTP version 2. · PTP transport over Layer 2 Ethernet (IEEE 802.3), IEEE 1588-2008, Annex F. · Multicast addressing. · Peer-to-peer (P2P) path delay measurement mechanism. · Capable of working with one-step and two-step master clocks. · Responds to peer path delay requests with two-step peer delay responses
(Pdelay_Resp, Pdelay_Resp_Follow_Up).

The 1588 ports can synchronize to the PTP grandmaster clock with sub-microsecond accuracy, which can be degraded by network topology, 1588 switch accuracy, or transmission media asymmetry.
To troubleshoot connectivity issues with 1588 switches, you can monitor the PTP clock status and time accuracy via Telnet using the “ptp” command, as shown in the following picture.

3.5 Synchrophasor Measurements
3.5.1 Synchrophasor Estimation
The PMU PRO calculates and reports synchrophasor estimates as defined and described in IEEE C37.118.1 Clause 4.
Phasor estimates include three-phase voltage and current phasors, as well as positive and negative sequence voltage and current phasors, calculated from input waveforms synchronized to an absolute time reference.
All measurements are made on a common time base and related to the system nominal frequency, so the phase angle measurements are directly comparable. Differences in the actual frequency are included in the phase angle estimation

PMU PRO Phasor Measurement Unit

3 Operating the PMU PRO

Instrumentation Measurements

3.5.2 Frequency and ROCOF Estimation
The frequency is computed as the first derivative of the synchrophasor phase angle, and ROCOF is computed as the second derivative of the phase angle.
The frequency and ROCOF estimates are based on positive sequence synchrophasors calculated using the symmetrical components transformation. Since phase angle changes relative to the difference between the actual frequency and the nominal frequency, this approach yields the offset from nominal.

3.5.3 Reporting Rates
The PMU supports data reporting at sub-multiples or multiples of the nominal system frequency. The actual reporting rate is user selectable. Reporting rates at 50 Hz system frequency:
Frames/s 1 2 5 10 25 50 100 200
Reporting rates at 60 Hz system frequency:
Frames/s 1 2 3 4 5 6 10 12 15 20 30 60 120 240

3.6 Instrumentation Measurements
Instrumentation measurements provide real-time measurements and one-second aggregation of voltage, current, per-phase and total power and displacement power factor, and voltage and current sequence components including voltage and current unbalance.
All electrical quantities are fundamental components and are based on voltage and current synchrophasor measurements synchronized to the device’s reporting rate.
See Appendix C for a full list of the measurements provided by the PMU PRO.
3.7 Instrument Transformer Correction
Ratio and phase angle error correction can be applied to external CTs and PTs to achieve overall metering installation accuracy, or be used in any installation to optimize the accuracy of the measurement data.
The user can configure the ratio correction factor and phase angle error covering the typical transformer operating range. See 5.2.2 “Transformer Correction” for information on how to set up ratio and phase angle error correction in your device.
3.8 Operating Logic Controller
The PMU PRO logic controller can perform various actions in response to user-defined internal and external events. Unlike a conventional PLC, the PMU PRO uses a simplified setpoint-based programming technique that allows you to define a logical expression based on measured analog or digital values and perform the actions you want when the operate conditions are met.
The logic controller provides 32 setpoints with programmable operate and release delays, each of which evaluates a conditional expression with up to 8 arguments. Whenever the expression evaluates to true, the logic controller can perform up to 4

3.9 Operating Device I/O

3.9.1 Operating Digital Inputs
The PMU PRO can monitor up to 25 digital inputs including one built-in digital input and others located on 3 expansion modules.
See 2.3 “Electrical Installation” for the connection diagrams and location of the digital input terminals.
All digital inputs have a programmable de-bounce time and can operate in static and pulse mode using normal (normally open) or inverting (normally closed) polarity. All inputs are sampled at a 1 ms rate.
See 5.2.5 “Configuring Digital Inputs” for information on how to configure the operation of the digital inputs in your device.

3.9.2 Operating Relay Outputs
Up to 13 relay outputs including one built-in relay and others located on 3 expansion modules can be provided with the PMU PRO for control and alarm indication.
See 2.3 “Electrical Installation” for the connection diagrams and location of the relay terminals. See Technical Specifications in Appendix A for relay ratings.
The relay outputs are updated at a half-cycle rate. Each relay is independently programmable and can operate in latched, unlatched, pulse or KYZ mode, and relay operations can be inverted so that the relay is energized when inactive and de-energized when activated.
The relays can be operated either locally via the logic controller or by a remote command sent through communications.
See 5.2.6 “Configuring Relay Outputs” for how to configure relay outputs in your device.
3.9.3 Operating Analog Input
The PMU PRO is equipped with one built-in optically isolated analog input with userselectable options for 0-20 mA, 4-20 mA, 0-1 mA, and 1 mA. The 0-1mA and 1mA inputs provide double overload up 2 mA.
See 2.3.4 “Built-in I/O Connection” for the connection diagram and location of the analog input terminals. See Technical Specifications in Appendix A for analog input ratings.
Updating the analog input is synchronized with the PMU reporting rate. The device automatically converts the raw analog input readings received from the A/D converter to a user-defined engineering scale and reports the input values in engineering units with configurable resolution.
See 5.2.7 “Configuring Analog Input” for information on how to set up the analog input in your device.

The PMU PRO uses the standard TCP and UDP port numbers assigned to the corresponding protocols by the Internet Assigned Numbers Authority (IANA) by default. For some protocols, such as DNP3 and IEEE C37.118.2, you can change the default port number through the protocol configuration.

TCP Communications

Keepalive Probes
The PMU PRO uses TCP keepalive probes to detect dead connections and prevent resource leaks. If the connection is idle longer than configured, the device sends a keepalive request to check if the connection is alive. If no response is received after 5 successive keepalive retransmissions, the connection is considered dead and will be closed.
The TCP keepalive idle time can be configured from 1 to 60 seconds or set to 0 to disable keepalive probes. It is set in the device to 20 seconds by default.
Client Connection Timeout
The client connection idle timeout can be used to terminate a connection if it has been inactive for too long. It can be configured from 1 to 300 seconds or set to 0 to disable the client idle timeout. It is set in the device to 120 seconds by default.
If the idle timeout is enabled, then the master station should periodically send probe requests to the device to maintain some kind of activity on the connection socket if it wants to keep the connection open.
When sending unsolicited messages via IEC 60870-5-104 or streaming data via IEEE C37.118.2, the device disables the connection timeout and uses keepalives regardless of port settings.
NOTE: To prevent resource leaks, the PMU PRO does not allow both the keepalive probes and connection timeout to be disabled. At least one of the dead connection preventers will always be active.

UDP Communications
Unlike TCP connections, streaming data via UDP does not provide tools for probing whether a client who initiated transmission is still alive and listening to the data stream.
Abnormal termination of client operations without explicitly disabling data transfer may leave the stream socket active and thus cause a resource leak. To avoid this, the device provides, where necessary, the appropriate means to manually stop active UDP streams and release the associated resources.

3.11.2 Telnet Communications
The PMU PRO comes with a Telnet server that can be used to monitor or check the current status and operations of the device. Run a “telnet” command with your device’s IP address, log into the device with your user password and enter a command from the suggested list.

If Windows does not recognize the “telnet” command, go to the Start menu, select “Settings”, click “System”, and then select “Optional features”. Click “More Windows features” in the top right, check the Telnet client checkbox, and click OK.

NOTE
Telnet access requires at least level 2 password authorization. After three unsuccessful login attempts, the Telent server will be shut down for one minute.
3.11.3 Modbus Communications
For detailed information about Modbus protocol implementation, register map and protocol parameter settings, see the PMU PRO Modbus Reference Guide.
Modbus protocol is used as a default communication protocol for communicating with the PMU PRO via PAS, remote configuring and monitoring the device, and retrieving event and data log files.
The Modbus TCP server uses the standard port number 502 assigned by IANA.
Modbus TCP Notification Client
The TCP notification client can establish connections with a remote Modbus/TCP server and send notification messages either on events, or periodically on a time basis.
Client connections are triggered via the logic controller.
See 5.3.3 “Configuring the TCP Notification Client” for how to configure the TCP notification client for your application.
eXpertPowerTM Client The eXpertPowerTM client provides communication with the eXpertPowerTM server SATEC’s proprietary Internet services. Connections to the eXpertPowerTM server are carried out via the Modbus/TCP protocol on a periodic basis managed by the eXpertPowerTM server.
See 5.3.4 “Configuring the eXpertPower Client” for information on configuring the eXpertPowerTM client in your device.

3.11.4 DNP3 Communications
For information about DNP3 protocol implementation, object reference and protocol parameter settings, see the PMU PRO DNP3 Reference Guide.
The DNP3 TCP port number is configurable via the DNP3 setup. By default, the DNP3 TCP server uses the standard port number 20000 assigned by IANA.
The PMU PRO implements Level 2 of the DNP3 communication protocol. The device does not support unsolicited requests or hardware collision avoidance.
The PMU PRO DNP3 implementation supports a wide variety of messages. The most common method of getting static object information from the device via DNP3 is issuing a read Class 0 request. The device allows free configuring the Class 0 response by assigning ranges of static points to be polled via Class 0 requests.
Any static object point is allowed to be linked to an associated event object point for generating data change events to be polled via event Classes 1, 2 or 3.
Up to 64 configurable event object points are available for generating events. The event scan period is half the power frequency cycle time for binary input points, and 200 ms for analog input and binary counter points.

3.11.5 IEEE C37.118.2 Communications
For information about IEEE C37.118.2 synchrophasor data transfer protocol implementation, communication features and protocol parameter settings, see the
PMU PRO IEEE C37.118.2 Reference Guide.
IEEE C37.118.2 TCP and UDP servers listen on standard ports 4712 and 4713, respectively, which can be changed in the protocol configuration.
The PMU PRO provides commanded client-server UDP and TCP data transmission and spontaneous UDP data transmission over IP protocol.
Synchrophasor data is transmitted at the device’s measurement/reporting rate. It is configurable through the basic device setup or through the IEEE C37.118.2 or IEC 61850 SV publisher settings.
Data Frames
Synchrophasor data frames transmit a time stamped set of measurements that include phasor estimates, frequency deviation from the nominal power line frequency or actual frequency, and the rate of change of frequency. In addition, the data frame can be expanded to contain analog data (total active, reactive and apparent power, and power factor) and digital input status information.
Phasor components can include three voltage and three current phasors, positive sequence voltage and current phasors, negative sequence voltage and current phasors, or all of them in one frame.
Complex phasor values can be sent in a rectangular coordinates format (real and imaginary) or in polar coordinates (magnitude and angle). Phasor and frequency data can be represented in 32-bit IEEE floating-point format or as 16-bit scaled integer numbers. When using the integer format, the data conversion factors are provided in IEEE C37.118.2 configuration frames.

Communicating with the PMU PRO

Configuration Frames
IEEE C37.118.2 configuration frames provide information about the synchrophasor data stream in binary format. The PMU PRO supports CFG-1, CFG-2 and CFG-3 configuration frames.
In spontaneous UDP data transmission mode, CFG-2 or CFG-3 configuration frames can be sent spontaneously without an explicit user command. When enabled, a configuration frame is sent periodically every 30 seconds.

Commanded Unicast UDP and TCP Data Transmission
Commanded unicast data transmission is enabled and disabled by commands sent by the IEEE C37.118.2 client over a UDP or TCP connection.
The PMU PRO provides 5 data streaming slots for continuous streaming synchrophasor data over unicast UDP or/and TCP connections.
Although the UDP server responds to commands from unlimited number of UDP clients and the TCP server can support more client connections, the commands to turn on data transmission on new connections after all 5 data streams are running will be ignored.
To avoid resource leaks due to dead UDP connections, the PMU PRO provides a command the user can send to the device through the IEEE C37.118.2 configuration dialog that stops all active commanded UDP streams and releases the associated data stream slots.
You can check which data streams are currently active via Telnet using the “188” command as shown in the following picture.

Spontaneous UDP Data Transmission
Spontaneous data transmission is enabled and disabled in the device by the user via the IEEE C37.118.2 settings. The destination UDP port and IP address are user-configurable.
Spontaneous UDP data transmission operates in unicast, multicast or broadcast mode depending on the destination IP address you specified.

3.11.6 IEC 61850 Communications
For information about IEC 61850 protocol implementation, communication and protocol parameter settings, see the PMU PRO IEC 61850 Reference Guide and PMU PRO IEC 61850 Conformance Statement (PICS, PIXIT, MICS, TICS) documents.
The PMU PRO IEC 61850 server supports IEC 61850-8-1 client-server and GOOSE communications and IEC 61850-9-2 sampled values communications, compliant with the IEC 61850 Ed2 set of standards.
PAS provides an IED configuration tool for customizing your device’s settings and exporting IED configuration description files (CID/IID) for use with IEC 61850 client applications.

IED Configuration Description File
The IEC 61850 device data model is described in the PMU PRO IED configuration description file “PMU PRO _2007B_RevXX.icd” provided with your device. Use this as a basic template to create custom CID and IID files for use in your installation.

Client-server Communications
By default, the IEC 61850 TCP server uses the standard port number 102 assigned by IANA.
The TCP server supports up to 5 client-server associations simultaneously.
The IEC 61850 TCP server by default uses TCP keepalives to detect dead connections. The client connection idle timeout can optionally be used to terminate an idle connection, and is normally disabled.

GOOSE Communications
The PMU PRO provides a GOOSE publisher for fast distribution of measurement data over Ethernet for real-time distributed control within a substation. The GOOSE publisher settings and GOOSE dataset can be configured using PAS.
GOOSE messages are continuously retransmitted across the multicast association using a configurable multicast MAC address. The fastest retransmission time is half-cycle for the first 5 messages after an event occurred, then geometric with a time multiplier of 2 until the maximum configured retransmission time.

Sampled Values Communications
The PMU PRO provides a multicast sampled values (MSV) publisher that is responsible for streaming synchrophasor data over Ethernet. The MSV publisher settings and sampled values dataset are configurable via PAS.
Synchrophasor data transfer in the context of IEC 61850 uses IEEE C37.118 to IEC 61850 mapping mechanism defined in IEC 61850-90-5.
PMU is modeled as a dedicated logical device within the PMU PRO IED. The detailed PMU data model is shown as part of the ICD definition file provided with your device.
IEEE C37.118.2 synchrophasor data stream is mapped to IEC 61850-9-2 sampled values APDU and the data rate is synchronized with the C37.118.2 synchrophasor data rate.

3.11.7 IEC 60870 Communications
For information about IEC 60870-5-101 and IEC 60870-5-104 protocol implementation, communication options, object reference and protocol parameter settings, see the
PMU PRO IEC 60870-5-101/104 Reference Guide.
The PMU PRO supports all standard ASDU types for data interrogation, event reporting and control.

TCP IEC 60870-5-104 Connections
The IEC 60870-5-104 TCP server uses the standard IANA assigned port number 2404.
Each Ethernet port can be configured for two redundant logic connections with the controlling station using two different IP addresses for spontaneous/cyclic transmission. Selecting the same IP address for both connections disables redundancy mode. In any case, both IP addresses must be defined to enable spontaneous/cyclic transmission.

Outstanding Messages
The controlling station must acknowledge receipt of information messages. The maximum number of outstanding (unacknowledged) messages allowed can be configured from 1 to 32. The default value is 12. When the number of unacknowledged messages reaches the maximum, the device pauses transmission until the controlling station sends an acknowledgement or restarts data transfer.

Interrogation
The PMU PRO supports general and group interrogation commands for binary and analog objects. Address ranges for general and group interrogation are configurable.
Up to 15 groups can be arranged for group interrogation. Any compatible ASDU data type can be separately selected for each range of points regardless of the configured default object type.

Cyclic Data Transmission
The object address range and transmission period for periodic/cyclic data transmission are configurable. The cyclic transmission period can be set from 100 to 30,000 ms, or set to 0 (default) to disable transmission.
Configured cyclic data is transmitted periodically over the active connection after the controlling station confirms start of data transfer.

Event Reporting
The PMU PRO provides up to 64 configurable setpoints for reporting events when the measured value exceeds a specified threshold or changes by a certain percentage, or the status of a binary point changes. The event scan period is half the power frequency cycle time for binary objects and 200 ms for analog objects.
Collected events are transmitted spontaneously over the active connection after the controlling station confirms start of data transfer.

Delta operators evaluate a logical expression to true if the following conditions are met:
· Delta: the absolute difference between the last reported value and the current value exceeds the specified threshold
· Delta+ (incremental delta): the positive difference between the current value and the last reported value exceeds the specified threshold
· Delta- (decremental delta): the positive difference between the last reported value and the current value exceeds the specified threshold
· rDelta (relative delta): the absolute difference between the last tested value and the current value exceeds the specified threshold
· rDelta+ (incremental relative delta): the positive difference between the current value and the last tested value exceeds the specified threshold
· rDelta- (decremental relative delta): the positive difference between the last tested value and the current value exceeds the specified threshold

Description None (no action) Raise an event flag Drop an event flag Operate relay Release latched relay Increment counter Decrement counter Clear counter Event log on setpoint operation, release or both Data recording to log file Send a notification to a remote TCP server

Using Logical Operators
Logical operators OR/AND are treated in a simplified manner. They have no specific priority or precedence rules.
Any trigger condition that is ORed in a logical expression and evaluates to true overrides any preceding condition evaluated to false. Likewise, any trigger condition that is ANDed in a logical expression and evaluates to false overrides any condition evaluated to true before it.
To avoid confusion, it is recommended not to interleave different logical operators in one expression. Instead, combine all conditions that use the same logical operator on one side of the expression, and the others on the opposite side.
To explicitly override all preceding conditions with a critical trigger, place it at the end of the logical expression using an OR operator if you want the setpoint to be operated anyway when the trigger condition evaluates to true, and with an AND operator, if the setpoint should not be operated while the critical trigger is not asserted.

PMU PRO Phasor Measurement Unit

5 Setting Up the PMU PRO

General Device Settings

Using Numeric Triggers
For numeric (analog) triggers, a setpoint allows you to specify two thresholds for each trigger to provide hysteresis (dead band) for setpoint operations. The operate limit defines the operating threshold, and the second release limit defines the release threshold for the trigger. Trigger thresholds are always specified in primary units.
If you do not want to use hysteresis, set the release limit to the same as the operate limit.

Using Binary Triggers
Binary (digital) triggers, as digital inputs, relays, or event flags, are tested for ON (closed/set) or OFF (open/cleared) conditions.
Binary triggers are divided into two types: static and pulsed. Static events are levelsensitive and are asserted as long as the corresponding condition exists, such as event flags or static digital inputs.
Pulsed events are edge-sensitive events with auto-reset, such as pulse inputs (transition pulses on digital inputs) and events generated by interval timers. The logic controller clears pulsed events at the end of each scan, so that triggers that used these events are prevented from being triggered once again.

Using Interval Timers
Interval timers are not synchronized with the clock. When the setpoint is activated, the timer is restarted and then generates the next timer pulse when the timer interval expires.

Using Time Triggers
Unlike interval timers, time triggers are synchronized with the device clock and can be used to program time-synchronized actions, such as synchronous recording interval data.

Delaying Setpoint Operations
Two optional delays can be added to each setpoint to extend monitoring setpoint for a longer time before making a decision on whether the expected event has occurred or not. If a delay is specified, the logic controller changes the setpoint state only if all conditions are asserted for a period at least equal to the delay time.

Setpoint Actions
When a setpoint state changes, that is, the setpoint event is either activated or deactivated, the following happens in your device:
· The new setpoint status is logged to the setpoint status register that can be monitored via communications in order to give an indication of the expected event.
· The status of the activated setpoint is latched in the setpoint alarm register, which is also accessible remotely. The register retains the last setpoint alarm state until it is explicitly cleared.

PMU PRO Phasor Measurement Unit

5 Setting Up the PMU PRO

Configuring Communication

· Up to four programmable actions can be performed when the setpoint is activated. Typically, setpoint actions are performed independently for each setpoint and can be repeated several times for the same target.
The exceptions are relay operations and data recording that are shared among all setpoints using an OR scheme for each target. The relay output is activated when one of the setpoints linked to the relay is activated and remains energized until all those setpoints are released.
