FOUR-PARAMETER SINE-FITTING ALGORITHM FOR DETECTION AND CLASSIFICATION OF TRANSIENTS AND WAVEFORM DISTORTIONS
Journal Title: Metrology and Measurement Systems - Year 2008, Vol 15, Issue 4
Abstract
This paper describes a new method for detection of some power quality (PQ) disturbances, namely transients and waveform distortions. The proposed algorithm is based on a modified version of the four-parameter sine-fitting algorithm. The sine-fitting algorithm is used to estimate the parameters of the power system’s voltage signal’s fundamental and to extract the transient component of the voltage. The performance of the proposed method is compared with previously developed algorithm and with two commercial PQ analyzers.
