Fault location using PMU measurements and wide-area infrastructure

摘要

Fast and accurate fault location is critical to restoration of the power system. Deployment of production grade Phasor Measurement Unit (PMU) based on the latest IEEE C37.118.1 measurement standards using high-speed “P Class” data makes accurate fault location possible. Multi-terminal PMU data and decentralized PDC storage can easily be leveraged to not only obtain affordable and accurate fault location but also provide the operator with key information. By-products of this process are dynamic computation of line positive-sequence impedance and fault resistance.
