摘要：

This paper describes a recursive algorithm suitable for microprocessor based power system relaying and measurement applications. The algorithm is designed using the least error squares curve fitting technique. The mathematical background for the non-recursive least error squares algorithm is extended to form a recursive algorithm. A method for including decaying dc and harmonic frequencies in the algorithm is described. Finally, sample studies are presented to demonstrate the performance of the developed algorithm.
