| Abstract: | A new algorithm based on the least square fit technique for m easuring power system frequency is presented.The algorithm has the advantage of less com putation and of fast response,and is free from the influence of the DC component. A preprocessing algorithm is also presented,which can effectively suppress the second harmonic and the third harm onic. Experim ental results show the effectiveness of the new algorithm for measuring power system frequency. |
