Abstract :
This paper discusses the evaluation of both off-line and on-line harmonic estimation techniques. For this purpose, the estimation of distribution system harmonics was performed by both techniques. In the off-line technique, the effect of sampling rate, harmonic order and outliers upon the accuracy of the estimated harmonics was discussed by the state space model. The on-line estimation was conducted by two different approaches: the time series analysis approach and the artificial neural networks (ANN) approach. A comparison between the results of the two approaches is presented
