Abstract

Power system frequency generates an important impact on operation, control and protection of the power system, and it is the important index of weighing power quality, so it is very necessary to measure it accurately. First, this paper uses the linear regression function to fit the signal including harmonic needed to be measured and the iterative reweighted least squares procedure is educed for signal spectrum analysis. Then, a new method to measure power system frequency is presented. In case of the few sample number, this method, using single frequency to sound out whether it can fit the original signal curve well or not, can measure power system frequency with accuracy by comparing different amplitude. Through discussing three examples and com paring with FFT, it can be proved that the new method has the characteristics of simple computation and high precision.
