电力系统广域测量与控制四川省重点实验室 Contents Introduction Secure state Security analysis-linear sensitivity analysis method
Introduction Power system not only needs to be economic, but more needs to be secure. System security:the system can continue to be in normal operation state after some devices get faulted. How to guarantee (enhance)system security? o Reserve Enhance the reliability of the devices Operator's decision making 电力拿镜广城洲量写控制四川省童点实验蜜 家电
