| Abstract: | A new power system frequency measurement method is proposed in this paper.The auto-correlation of power system frequency which consists harmonic wave and DC component is analyzed and do multi-layer autocorrelation and two times derivative to the power system frequency.The Geometric theorem is applied to console the zero problem of denominator and get the analytical expressions of power system frequency,Influence factors are analyzed and simulation experiment shows the method is effective. |
