| Abstract: | A new method based on zero crossing is presented for estimating power system frequency.This method can estimate power system frequency precisely through simple calculating and follow the tracks of the frequency deviation quickly.In this paper,some simulation are presented for evaluating the influences by harmonics and random noises,and the property for following the tracks of the frequency deviation. |
