摘　　要：2008年的罕见冰灾暴露了电力系统规划方面的缺陷,也透视了目前停电防御系统在广域信息、仿真分析、决策支持这3个核心功能上的不足。为了有效应对极端外部环境引发的巨型停电灾难,提出停电防御系统至少应增加的功能,包括:将气象和地质等非电气信息引入防御系统,分析相应的风险并及时预警;将在线预评估功能从针对固定的故障集,提升到跟踪外部环境,动态识别高风险的潜在相继故障,进行风险评估及风险管理;支持恢复控制的自适应优化决策,代替离线制定的少量预案。从而使预防控制、紧急控制、校正控制和恢复控制能更有效地协调处置极端外部灾害引发的复杂故障场景和停电模式。The infrequent ice disaster in 2008 not only exposes the irrationality of current standards on power system planning, but also shows the insufficiencies in the blackout defense system newly commissioned, called WARMAP （EACCS）, if extreme external disaster is encountered. In order to overcome such deficiency, the following functions are proposed for realization. ①Importing meteorological, geological and other relevant non-electrical information to the defense system, assessing the corresponding risk and giving early warning in time. ②Upgrading the online security assessment function from aiming at a set of pre-fixed faults to aiming at the cascading contingencies with high-risk identified with considering the evolutions of both external conditions and power system. ③Supporting adaptive optimal restoration control instead of a restoration procedure that based on a few offline prepared cases. Therefore, preventive control, emergency control, corrective control, as well as restoration control can effectively deal with complicated fault scenarios and outage natterns.
