In the power systems, frequency is an important parameter for harmonic analysis. This paper proposes a modified high precision zero-crossing detection method. The high frequency noise will affect the power system’s frequency measurement, FIR processing is used for the power signal. Simulation shows that after effective De-noising or when the signal-to-noise ratio (SNR) is higher, the method can reach the precision of 0.01Hz and meet the requirements of frequency measurement precision.
