| 摘 要： | 间谐波的频率是基频的非整数倍,会导致电压波形的均方根值和峰值发生波动进而引起闪变.分析了间谐波与闪变之间的量化关系,讨论了多个间谐波共同作用时对总闪变效应的影响;通过研究国际电工委员会(IEC)闪变仪测量方法的原理,指出其在测量间谐波闪变时的不足,并提出一种基于频域法的算法来评估间谐波闪变效应,该算法通过频谱分析来获取...

| Abstract: | Interharmonics,whose frequencies are not integral number of the fundamental frequency,will lead to the rms value and the peak value fluctuation in the voltage waveform which in turn leads to flicker.The quantitative relationship between interharmonics and flicker is analyzed,and the total effect induced by a number of interharmonics is discussed.By studying the IEC flicker measurement principle,the deficiencies in its use for the interharmonics-fliker measurement is pointed out,then a method based on the fr... |
