基于改进的FastICA算法的电压闪变检测
Voltage flicker detection based on improved FastICA algorithm
摘要
Abstract
This paper presents a voltage flicker detection method based on an improved fast independent component analysis (FastICA) algorithm. The multiplicative result of flicker signal and synchronizing voltage which has the same phase and same frequency with the fundamental wave is transformed into the signal combination of envelope signal and double side band modulated signal with 100 Hz as its central frequency: with improved FastICA algorithm, voltage flicker signal separation is then carried out according to the independency principle of maximizing Negentropy. In order to approximate the real signal better, the paper amends the amplitude value of the separated signal and finally achieves the voltage flicker detection. Simulation results show that this algorithm is correct and feasible.关键词
