摘 要：變電站并聯電容器電抗率的選擇主要基于限制涌流、抑制諧波的考慮。提出了電抗率混裝配置方案的簡化計算及校驗方法，并從兼顧諧波抑制及經濟性方面就某具體工程進行了方案比選。結果認為變電站低壓側并聯電容器電抗率宜采用4.5%(5%)與12%混裝方案，500kV變電站可每臺主變低壓側配置一臺12%電抗率并聯電容器。
關鍵詞：并聯電容器；電抗率；諧波

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
