The Flicker Detection Based on the Voltage RMS Calculating by Sliding Window
摘要
Abstract
In order to realize the accurate measurement of voltage flicker parameters, this paper introduces a flicker detection method by calculating the voltage RMS values. The way to implement the method is first to calculate the voltage RMS by a sliding window, to elect the window width as a power frequency cycle and the adjacent windows half cycle overlap. After removing the mean component from the voltage RMS to carry through FFT, the flicker frequency is directly obtained, the flicker amplitude can be obtained accurately through the look-up table correction. The simulation results show that this method is not affected by high harmonics, and can realize accurate measurement of multi-frequency voltage fluctuation.关键词
