2 U/ A. B2 L. K7 }( l/ \& y- y% m7 t& o; Q' r/ u0 u8 S
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？
+ `. ~' d; Z9 n/ Z O! E# s
8 @6 [+ K7 [% M3 U+ F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。
. @7 m1 a7 Z' f1 x( E: i
# u" B; l$ d) E; ?- d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？
