消谐电抗电容器补偿系统在变电所中的应用

Use of Reactor/Capacitor Series for Harmonic Elimination in Transformer Substation

分析了消谐电抗电容器组补偿系统在低压变电所应用的原理,探讨如何选择电抗电容器组及其应用;通过实际应用现象并对谐波进行测量,揭示谐波对电容造成的危害原因。研究结果表明:电容电抗回路的串联调谐频率低于最低次谐波频率时,可有效抑制谐波对电抗电容器组的危害。

With regard to the harms of harmonic wave to the capacitors in the transformer substation, the author explains the function of a compensation system with reactor/capacitor series for harmonic elimination and discusses the selection and use of such series. The results show that when the tunning frequency of the reactor/capacitor circuit is lower than the lowest harmonic frequency, the harms of harmonic wave to the reactor/capacitor series can be effectively inhibited.
