电网谐波分析的一种实用方法

A Practical Method for Analysing the Harmonics of Power Systems

作者依据多年分析电网谐波的经验,总结了目前谐波分析中理论分析与实测结果相差的问题,说明了其原因和相应的解决方法。并针对文献中的理论分析方法,尚不能完全适用于实际电网的情况,提出了一种实用的电网分析方法—敏感度摄动法,在实际应用中取得了良好的效果。

The authors summarize the problems in analyzation of power systems' harmonics at present in terms of their many years' experiences. The main problem is that there is a big difference between analytical results and on-the-spot measurement results. The authors describe the possible reasons and corresponding resolutions, and present a practicable method-sensitivity perturbation method. Sensitivity perturbation method achieves good resuits in analyzing harmonics of real power systems.
