DPSP 2020

What to Expect

Visit the RTDS Technologies booth at DPSP for a live hardware-in-the-loop demonstration of full-digital protection system testing. A relay will be connected to the simulator for HIL testing using IEC 61850 GOOSE and Sampled Values. The RTDS® Simulator is the leading real-time simulation tool for protection system development and testing.

We would be happy to meet with you to answer questions and to learn how real time can be adapted to your protection system testing needs. Our Dinesh Gurusinghe will also present a paper on performance evaluation of PMUs with Sampled Value input using our updated PMU Test Utility. Catch his presentation on Tuesday, March 10 at 12:45 p.m. (Session 2b: Condition Monitoring and Situational Awareness).

Please see below for an abstract:

Abstract

Synchrophasors produced by phasor measurement units (PMUs) are widely used in modern power systems for wide-area monitoring, protection and control applications. Contemporary technology allows a PMU to acquire its instantaneous voltage and current inputs digitally from sampled values (SV). This work investigates the electrical performance of two commercial PMUs with SV input in accordance with prevailing IEC/IEEE standards. The paper also presents a performance comparison of PMUs with SV input against ones with conventional hardwired analogue input. A digital real-time simulator is used to generate theoretical test signals and publish SV (as per IEC 61869-9) into PMUs under test. Both steady-state and dynamic performance of PMUs are evaluated using a test automation and analysis tool. It is evident from the results obtained that PMUs with SV input, when correctly interfaced, produce robust and accurate measurements.
