Abstract

With the widely installation of Phasor Measurement Units (PMUs) in power system and the increasing requirement of the real-time monitoring and control, a novel power system topology analysis algorithm is proposed with high precise information from PMUs to improve the performance of current network topology analysis. First of all, a method of identifying switch status is established to correct the state mistake of circuit breakers (CB) relying on the analog data acquired by PMUs. Subsequently, a topology analysis in substation combined with the PMUs information (including the digital data of CBs state and the phasor of voltage and current) is advanced in this paper. And then an efficient topology analysis algorithm introduces into topology search process using Cotree-to-Bus structure array. Finally, simulation results based on the PSCAD and MATLAB software have validated the efficiency and accuracy of the novel method introduced in this paper.
