摘 要:為提高閃變儀的測量精度,在介紹IEC閃變儀的測量原理及短時閃變嚴重度計算方法的基礎上,論述了閃變儀的數字化實現模型及PID自校驗控制算法的實現,并采用統計排序法計算短時閃變嚴重度。針對不同波動頻率下短時閃變嚴重度的測量誤差引入多項式擬合校正,Matlab仿真結果表明,引入多項式擬合校正方法明顯提高了閃變儀的檢測精度。
關鍵詞:閃變;短時閃變嚴重度;自校驗;誤差校正

Abstract:In order to improve the measurement precision of the flicker meter, on the basis of the IEC flicker meter measurement principle and the calculation methods of the short-term flicker severity, this paper discussed the model of digital flicker meter and the PID self-checking control algorithm, at the same time, the short-term flicker severity was calculated with statistic sequence. In allusion to the measurement error of the short-term flicker severity in different fluctuation frequency, polynomial fitting correction method was introduced and verified by the Matlab simulation experiment.
Key words: flicker; short-term flicker severity; self checking; error correction
