Abstract:This paper described a new algorithm for measuring frequency.This method is based onthe curve fitting technique with only three points and uses multi-point frequency compensa-ting technique to avoid voltage cross-zero point errors indroduced by harmonic terms are re-duced effectively in the algorithm without filter.Analysis and digital simulation show thatthe method provides a fast,simple and reliable frequency measurement with accuracy.
Keywords:frequency frequency measuring power system
