摘 要：变电站并联电容器电抗率的选择主要基于限制涌流、抑制谐波的考虑。提出了电抗率混装配置方案的简化计算及校验方法，并从兼顾谐波抑制及经济性方面就某具体工程进行了方案比选。结果认为变电站低压侧并联电容器电抗率宜采用4.5%(5%)与12%混装方案，500kV变电站可每台主变低压侧配置一台12%电抗率并联电容器。

Abstract:Selection of substation parallel capacitor reactance rate is basically in consideration of restricting surge current and restraining harmonics. This paper raised a simplified calculation and calibration method of reactance rate conventional disposition. Scheme comparison selection was carried out in concurrent of harmonic restriction and economic aspect from a certain project. The result shows that at substation low-voltage side the conventional scheme which adopted the parallel capacitor reactance rate of 4.5% to 5% combined with that of 12% is suitable. For 500kV substations, a 12% reactance rate parallel capacitor is disposed at each main transformer low-voltage side.
Key words: parallel capacitor; reactance rate; harmonic
