Experimental analysis for online estimation of power system parameters

Power system parameter plays a major role in operation, monitoring and controlling of electrical devices. Frequency and harmonics are the two vital parameters which influence different relay functionality of power system. Here, the estimation of frequency and harmonics of measuring voltage or current signal have made in presence of random noise and distortion. In this paper least square (LS) recursive least square (RLS) algorithm are used for measuring the parameter from the distorted voltage signal. The performance analysis of these algorithms has been performed through simulation. The experimental setup has been made to evaluate the robustness of the above algorithms.
