Milos Sedlacek, Zdenek Stoudek

Abstract

This paper presents an overview of algorithms for one-phase active power estimation using digital signal processing in time domain and in frequency domain and compares properties of these algorithms. Besides comparing already published algorithms also a new algorithm and additional information concerning some known algorithms is included. Results of computer simulations in Matlab and results of measurement by means of computer plug-in boards, both multiplexed and using simultaneous signal sampling is presented. Using new cosine windows designed by iterative algorithm recently published by this paper authors is also included.
