Abstract

Pollution of noise, frequency deviation and harmonics may make operating problem of devices in power systems. An extended real model of Kalman filter which is suitable for harmonics estimation of power system is proposed in this paper. Not only the frequency deviation is observed, but also the result is with a better accuracy, even if the power signals are influenced by noise. Finally, the performance of the proposed method is verified with a simulated signal over Lab VIEW program.
