AN INSIGHT IN PMUS FOR POWER SYSTEM STATE ESTIMATION

State estimators play an important role in electrical power system. There are of prime importance when it comes to observability analysis, detection of bad data and its correction, finding errors in parameters and topology. This paper discusses the role of Phasor Measuring Unit (PMUs) in Power System state estimation. The paper is aimed at giving an insight for this technology. It highlights the PMU architecture, working and its importance in the current scenario. The WLS algorithm which can be applied to the synchrophasors is also given here. The paper aims to provide information in a tutorial way about PMUs and their role in state estimation of power systems. Cite this Article: Anadi Shankar Jha, An Insight In PMUS For Power System
