This paper presents an approach for the detection of voltage and current harmonics. The demanding use ofnon-linear loads and power converters in the industry has distorted the voltage waveform profile. The presence ofharmonic distortion in transmission network, results in increasing power loss and also creates interference problems incommunication systems, so the active filters are used for harmonic elimination. For designing of the harmonic filter, itis necessary to obtain the perfect measurement of harmonic level. It represents a robust algorithm based on Kalmanfiltering. Extended Kalman filter algorithm is used to design optimal filter for measuring magnitudes and frequencies ofharmonic components present in non-sinusoidal voltage with existence of random noise in power system and distortionsagain taking into account the measurement noise and compare with inbuilt function FFT analysis in Matlab.
