摘 要：變電站并聯(lián)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(jiǎn)化計(jì)算及校驗(yàn)方法，并從兼顧諧波抑制及經(jīng)濟(jì)性方面就某具體工程進(jìn)行了方案比選。結(jié)果認(rèn)為變電站低壓側(cè)并聯(lián)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(tái)主變低壓側(cè)配置一臺(tái)12%電抗率并聯(lián)電容器。

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
