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？: m1 L: g2 J! g: i, s) Q
& g1 H# R( e! f4 Q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。* i1 o7 S* Q/ _' j' e1 x% d5 D+ p$ C
2 }: m4 D2 x& m) T: B3 ^/ z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？
