附錄一 諧振容量計算
發(fā)生n次諧波諧振的電容器容量，按下面近似計算式計算
 (附1.1)
式中Qcx--發(fā)生n次諧波諧振的電容器容量(Mvar)；
Sd--電容器裝置安裝處的母線短路容量(MV·A)；
n--諧波次數(shù)，即諧振頻率與電網(wǎng)基波頻率之比；
A--電容器裝置每相感抗(XL)與每相容抗(Xc)的比值，
即 A=XL/Xc
附錄二 電容器組投入電網(wǎng)時的涌流計算
一、單組電容器投入時涌流的計算
附圖2.1 單組電容器涌流計算值電路圖
L0-網(wǎng)絡(luò)每相等值電感；L-串聯(lián)電抗器和接線每相電感；
C-電容器組每相電容；DL-斷路器
