Technology of Phase Selection of AC Apparatus Based on FFT

Du Taihang Chen Peiying Mi Yanzhi Liu Xin (Electric and Automation School of Hebei University of Technology Tianjin 300130 China)  
The technology of phase selection always involves not only the detection of signal frequency,signal phase and power factor but also calculation and control of phase.And now electronic circuit used widely in phase selection devices realizes these functions.But there are some problems in the aspects of economy and reliability,even if using CPU,if may bring the problems of calculation methods.This paper expatiates on how to use Fast Fourier Transform Algorithm(FFT) to calculate signal frequency,signal phase,power factor.At the same time it also introduces the theory and realization method of phase selection.The phase selection device,which based on the technology mentioned above and single chip computer,is given at the last of the paper.This device used in the test equipment of the breakers can eliminate transient current in the experiment.
