摘　　要：在IEC闪变仪的基础上提出一种新的电压闪变测量方法,将二次采样和插值算法相结合,有效地检测出电压信号中的波动成分。仿真实验结果表明,该方法不仅能对低频率间谐波引起的电压闪变进行准确的测量,而且能对高频率间谐波引起的电压闪变进行测量和评估。Based on IEC flicker meter, a new approach to measure voltage flicker is proposed. Integrating secondary sampling with interpolation algorithm, the proposed approach can effectively detect the voltage fluctuating components. Simulation results show that using the proposed approach, not only the voltage flicker caused by low-frequency interharmonics can be accurately measured, but also the voltage flicker caused by high-frequency interharmonics can be measured and evaluated.
