高次谐波对低压无功功率自动补偿装置的危害及预防措施

Higher-order Harmonic Wave′s Damage to Self-compensating Device for Low-voltage Reactive Power and its Preventive Measure

通过对实际运行中低压无功补偿失效的原因分析 ,论证了谐波污染对无功功率补偿的影响 ;提出了谐波污染程度的简易估算方法及相应的抗谐措施 ,这些方法有效易行 。

Through the analysis to the cause of low voltage reactive compensation invalidation in actual operation, it is proved that the harmonic pollution can affect the reactive power compensation. It brings forward the easy estimate method to harmonic pollution and the measure of anti-harmonic. The method is easy to operate and has strong utility value.
