摘要：
A new algorithm based on the least square fit technique for measuring power system frequency is presented . The algorithm has the advantage of less computation 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 harmonic. Experimental results show the effectiveness of the new algorithm for measuring power system frequency.
