Project Objective

The objective of the project was to develop, test, demonstrate and provide a Synchrophasor Data Validation and Conditioning Application (SDVCA) that can be used by WECC and owners of synchrophasor data in the Western Interconnection to validate and condition synchrophasor data. The project period was from March 2014 - December 2015 and was completed in December 2015.

Scope of Project

Deliver Synchrophasor Data Validation and Conditioning Application (SDVCA) to WECC with dual validation and conditioning capabilities that are a sequential combination of primary and secondary conditioning from two applications:

The SDVCA will validate and condition synchrophasor data so that it can be used for analysis and real-time monitoring. This is expected to improve power system reliability by providing real-time situational awareness to grid operators. Collected information is also expected to improve the accuracy of the system model used in contingency analysis. The block diagram is shown in figure below:


The SDVCA addresses the problem of data quality. Many utilities have problems with data loss and errors, so are reluctant to use it for important applications. This application detects and indicates errors to help ensure that the delivered data is dependable. The model less approach is limited to detecting problems with data formats and measurement considerations. It doesn't have a way to check accuracy against a reference. The LSE based approach provides that capability by putting all the measurements into a structure based on their connections together. With this application the data can be both validated for accuracy and replaced by better estimates. This further assures the user of the data quality for use in other applications.

About EPG

Electric Power Group, LLC (EPG) has been pioneering the development and deployment of synchro-phasor technologies since 2000. Our principals have extensive experience in running and managing utility grids, investigating root causes of major blackouts (WECC 1996, EI 2003), and leveraging this deep domain knowledge to develop industry leading synchrophasor technology applications for wide area real time monitoring, visualization and situational awareness.

The EPG team has extensive hands-on experience with synchrophasor standards, networks, system architecture, deployments and performance analysis through work at EPG for leading ISO's and utilities including PJM, NYISO, ERCOT, CAISO, MISO, BPA, TVA, SCE, AEP, LADWP, SRP, Duke, Dominion, NYPA and other companies.
