摘 要:为提高闪变仪的测量精度,在介绍IEC闪变仪的测量原理及短时闪变严重度计算方法的基础上,论述了闪变仪的数字化实现模型及PID自校验控制算法的实现,并采用统计排序法计算短时闪变严重度。针对不同波动频率下短时闪变严重度的测量误差引入多项式拟合校正,Matlab仿真结果表明,引入多项式拟合校正方法明显提高了闪变仪的检测精度。

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
