故障解列与失步解列的协调优化

解列控制既可由故障驱动（即第二道防线中的故障解列），也可由轨迹驱动（即第三道防线中的失步解列）。对完全确定性的理想情况，只需要考虑故障解列，以减少对系统的冲击;但客观存在的不确定因素模糊了连锁解列的充要条件，突出了失步解列及两者协调的重要性。将解列后使各孤立子系统稳定的最小控制代价与故障概率的乘积之和作为解列风险，并按该指标协调2种解列方案。采用“在线预算、实时匹配”的方法提高故障解列的自适应性;由控制中心站、就地主站和解列装置组成自适应失步解列系统。其中，控制中心站负责应对振荡中心的转移;就地主站按断面功率或风险代价在线判断最优的解列割集。通过仿真验证了其有效性。

Optimization and Coordination of Fault-driven Splitting and Out-of-step Splitting

Splitting can be driven by either faults(fault-driven splitting performed at the second defense line),or trajectories(out-of-step splitting performed at the third defense line).Under Absolutely deterministic conditions,only fault-driven splitting is needed to reduce impact on power systems.However,there are many of non-deterministic factors which weaken the necessity of fault-driven splitting but emphasize out-of-step splitting and the importance of coordinating them.Multiplying the control cost of all isol...
