Filter design of frequency measurement for power system based on AC sampling

SHI Wang_wang, HUANG Ya_zhong (Electric Engineering Department of Yangzhou University,Yangzhou 225009, China)  
The method of FIR filter design for calcuating frequency in power system is presented.In this method the two quadrature FIR filers are designed to calculate frequency whose amplitude gain variation are very small and phases are linear.The simulating result shows the method is simple and precision.
