6%电抗率补偿装置对4次谐波放大的影响研究

Study of the Effect of Compensation Device with 6% Reactance Rate on 4^(th) Harmonic Amplification

通过对偶次谐波存在的条件及常见无功补偿电抗率串并联谐振点的分析,结合工程实测数据与仿真分析对比,研究了6%电抗率的补偿装置逐步投入系统对4次谐波谐振放大的原理,并提出了避免4次谐波放大的建议方案。

Based on the analysis of the conditions for the existence of even harmonics and the series and parallel resonant points of common reactance rate for reactive power compensation, and combining with the comparison of measured data and simulation analysis, it studied the principle of 4th harmonic amplification when the compensation device with 6% reactance rate was turned on step by step, and proposed schemes to avoid it.
