. K7 C3 E: G4 U1 g" M ^BPA潮流计算结果中，每条线路最后都会有一项QC，比如，Bus1到BusA最后一项是4.7QC，这个项到底代表的是什么意思？
. Q2 l7 y* _( d. F% H: N7 B" u) F/ v' a. K" `
另外下面SUMMARY OF SYSTEM QUANTITIES FOR ZONE 01中，有一项是LINE INJECTION (QC) 72.3，这个72.3是上面潮流计算中所有的QC项相加的结果，这一项代表什么意思？如果将这一项加进去的话，无功似乎无法平衡了。, c7 B/ A B; l. G5 X: y3 i1 h
2 @+ d: C- k: {6 k/ ?
在SYSTEM INJECTION: 中SUBTOTAL (INJECTION) 3.4 -23.5 显示系统缺少23.5Mvar的无功，为什么下面LINE AND TRANSFORMER LOSSES -3.4 23.5 这一项却显示是正值。显示正值是不是说明这项是线路的分布电容所发出的无功？如果指的是线路的分布电容所发出的无功，那么恰好可以补偿上面系统所缺少的无功。这样子的话那项72.3又要做何解释？5 v: t* J; _* ~* U+ x2 Q. L
