这是Carson W. Taylor的电压稳定性巨著Power system voltage stability里面chapter6: Simulation of Equivalent System里面的一页, 图为系统某条母线处的V-Q曲线, 该母线处为了保证电压稳定性加了SVC. 里面有一句话怎么也琢磨不透:
/ c" |" \/ T. Y  h( Y3 d/ }2 p(划红线的话)Following the outage, the operating point would immediately move from point A to point B. Within a few cycles, however, the system would stabilize near point C. 但是哪位大哥能解释下系统运行点从A到B的轨迹(红圈处)是神马?
