• New minimum power setting reduced to 0.2%Pn for large generator reverse power applications
• New user curves for overcurrent, voltage dependent overcurrent, earth fault, SEF, under/overvoltage, NVD, V/Hz for creation of user specific characteristics eg for undervoltage fault ride through applications
• Independent voltage dependant overcurrent (51V) and underimpedance (21) protection New field failure directional line and increase in setting ranges for field failure elements
• New 3rd stage of undervoltage protection
• New cybersecurity
• New PSL counters and timers settable in PSL or in settings enables more complex logic schemes to be created such as equivalent logic to TP2xx pole slipping (de-synchronisation) relay
• A large range of communications protocols including IEC61850 8-1 and new DNP 3.0 over Ethernet
• New XCPU3 with extended memory, new opto input and PSU design (P and M hardware)

Enabling Synchrophasor Based Wide Area Monitoring 

Reduce synchrophasor based wide area monitoring deployment and maintenance cost by integrating more PMUs per PDC, while being compliant to NERC-PRC-002-2 dynamic disturbance recording requirements: 

• Integration of Phasor Measurement Units (PMUs) 
• Seamless Interface to Super PDCs 
• Integrate any C37.118 compliant device

The Multilin P30 Phasor Data Concentrator is a modular, substation rated, high performance device capable of collecting, processing, recording and archiving C37.118 compliant synchrophasor data. The Multilin P30 supports up to forty PMU or PDC inputs and up to eight user configurable channels for transmission of synchrophasor data to clients such as other PDCs, Super PDCs and/or EnerVista Synchrophasor Viewer.

PRC-002-2 Dynamic Disturbance Recording (DDR)

PRC-002 is a standard under development that will define the requirements for recording and reporting Sequence Of Events (SOE) data, Fault Recording (FR) data, and Dynamic Disturbance Recording (DDR). The purpose of the standard is to facilitate analysis of disturbances.

FR and SOE are features commonly available today in protection relays and SCADA equipment.

The third type of recording defined in the PRC-002-2 standard is DDR. Large interconnected systems can have inter-area responses to each other resulting in slow oscillating load swings. These disturbances are characterized by oscillating power swings that can have frequencies in the neighborhood of 0.1 to 4Hz, and duration in the range of a few seconds to minutes or hours.

A dynamic disturbance recorder is a device cable of recording incidents that portray power system behavior during dynamic events such as low frequency (0.1Hz - 4Hz) oscillations and abnormal frequency or voltage excursions.

The advanced high capacity disturbance and event recording features available in the Multilin P30 Substation Phasor Data Concentrator support the requirements of the PRC-002-2 standard and can significantly reduce the time needed for analysis and reporting of disturbance analysis and regulatory reports.

Multilin P30 Built-in Historian Capabilities 

A typical GE Vernova substation Dynamic Disturbance Recording (DDR) system comprises of several PMUs reporting synchrophasor data at various different rates from 1 to 120 frames per second to a Multilin P30 PDC. Each of GE Vernova's Multilin PMUs may include 1 to 14 sets of phasor values (Multilin N60). Below are some typical examples of different types of PMUs with various combinations of phasor, analog and digital parameters. Large volumes of data generated by a DDR system requires a fast and reliable archiving method to guarantee data integrity for future analysis.

The Multilin P30 PDC historian processor is a high capacity platform capable of recording up to 100.000 values per second.

Local Archiving 

Distributed synchrophasor data storage through local archiving is recommended under the following two scenarios:

• 1. Upstream communication channels don't support the bandwidth to report all data monitored by the PDC.
• 2. Communication channels supports transmission of all data monitored by the Multilin P30 PDC. Archiving at the Substation level is 
      introduced to increase system reliability and preserve monitored data in case of upstream channel communications failure.

EnerVista™ P30 Setup Software

The EnerVista P30 Setup software follows the user friendly structure characteristic of the industry leading EnerVista suite of software applications.  

The EnerVista P30 Setup application provides easy access to the Multilin P30 PDC feature set through an intuitive tree view of the Multilin P30 parameters for a clear and simple configuration process. A series of convenient trouble-shooting and diagnostic tools such as trending, Multilin P30 sequence of events recorder live view of actual values is available in EnerVista P30 Setup to optimize the testing, commissioning and monitoring activities.

The Multilin P30 Setup software can operate without a Multilin P30 device physically connected to the computer allowing users to work on configuration projects and save settings in a configuration file for future use.

EnerVista Synchrophasor Viewer is a powerful yet simple to use synchrophasor data management and visualization tool. EnerVista Synchrophasor Viewer can be customized to provide different views of the power system in a time aligned, live view or time aligned replay of historical events over user defined time span.

The visualization interface is based on an easy to use "worksheet" work environment. Users can create multiple worksheets on which multiple user configurable objects such as Phasor Displays, Trend Charts, Historian Statistics and PMU Status tables are displayed.

EnerVista Synchrophasor Viewer supports up to 16 Multilin P30 historians simultaneously. Each historian can be accessed by up to seven concurrent users.
