Performance Evaluation of Modified Least Square Algorithm in Dynamic Events

摘要

As the population is increasing rapidly, Energy demands also needs to be fulfilled efficiently, for that supervision and monitoring of power system in various dynamic events have to be done precisely, Such tasks are normally done by Supervisory control and Data Acquisition System(SCADA) and Phasor Measurement Unit(PMU) also. PMU is best among all in terms of accuracy and time delaying as it uses Global Positioning System for synchronization with other PMU's, and strong phasor estimation algorithm with less number of samples giving accurate and real time tracking of power system in normal events as well as dynamic events. This paper evaluates Modified Least square method for various dynamic events as per IEEE standard of synchrophasor measurement. Morever dynamic events taken here are not model based signals, in earlier literatures model based signals were used, that problem is eliminated in this paper..
