Real-Time Testing of Synchrophasor-Based Wide-Area Monitoring System Applications Acknowledging the Potential Use of a Prototyping Software Toolchain

Abstract

This article presents a study on real-Time testing of synchrophasor-based "wide-Area monitoring system's applications (WAMS application)."Considering the growing demand of real-Time testing of "wide-Area monitoring, protection, and control (WAMPAC)"applications, a systematic real-Time testing methodology is formulated and delineated in diagrams. The diagrams propose several stages through which an application needs to be assessed (sequentially) for its acceptance prior to implementation into a production system. However, only one stage is demonstrated in this article which comprises the use of a prototyping software toolchain and whose potential is assessed as sufficient for preliminary real-Time testing (PRTT) of WAMS applications. The software toolchain is composed of two components: The MATLAB software for application prototyping and other open-source software that allows ingesting prerecorded phasor measurement unit (PMU) signals. With this software toolchain, a PRTT study is presented for two WAMS applications: "testing of the PMU/phasor data concentrator (PDC)"and "testing of wide-Area forced oscillation (FO) monitoring application."
