间谐波对闪变影响的量化分析

基于现有的电压闪变的约束条件，提出针对间谐波的约束条件，该约束条件由间谐波幅值与间谐波频率的关系曲线来表示，称之为间谐波-闪变曲线。由于白炽灯和荧光灯对电压有效值和峰值的敏感程度不同，所以分别基于电压有效值和峰值建立不同的间谐波-闪变曲线。研究结果表明，频率较高时，间谐波引起的电压峰值的波动要比电压有效值的波动更加显著。

Quantifying Flicker Impact of Interharmonics

A limit for interharmonics by utilizing the published limits on voltage flicker is proposed. The limit is presented as an interharmonic-magnitude versus interhar- monic-frequency curve and is called as interharmonic-flicker curve. The interharmonic-flicker curves based on the root- mean-square (RMS) and peak magnitude fluctuations are both derived, as incandescent and fluorescent lamps react differently to voltage RMS and peak fluctuations. The results reveal that the modulation impact of interharmonics on the RMS value is less significant than that on the peak value at high inter- harmonic frequency.
