A Hardware-In-The-Loop Configuration for Real-Time Power System Monitoring

Abstract

Wide area monitoring systems (WAMS) provide synchronized phasor measurement technology to significantly aid operators in online monitoring and controlling the power system. Under this premise, this paper presents the hardware and software configuration used for real-time monitoring of the IEEE 14-bus benchmark system simulated using the Real-Time Digital Simulator (RTDSTM). The proposed scheme involves remote terminal units (RTUs) implemented in RSCAD software, along with hardware phasor measurement units (PMUs), and a software phasor data concentrator (PDC). In the lab-scale platform, an online hybrid state estimation (HSE) algorithm is developed and demonstrated for the real-time monitoring of the IEEE 14-bus benchmark system.
