Phasor Measurement Unit based Fault Detection using Tellegen's Theorem in Geographically Zoned Power Systems

To ensure system stability and minimize downtime, it is imperative to rapidly and precisely identify faults in power systems. This study proposes a method that utilizes Phasor Measurement Units (PMUs) and Tellegen's theorem for fault detection. The power system is divided into zones based on geographical and electrical attributes, with PMUs strategically positioned in each zone to monitor voltage and current phasors. By applying Tellegen's theorem to the collected data, faults within these zones can be pinpointed. Experimental results on an 8-bus power system demonstrate the effectiveness of this approach, showing both accurate fault identification and reduced computational complexity. The simulation modeling of IEEE 8 bus system is performed on the platform real time digital simulator (RTDS/RSCAD).
