静态安全分析系统中考虑备自投动作的潮流确定方法
摘要：
一种静态安全分析系统中考虑备自投动作的潮流确定方法，属控制领域。其在所述的在线静态安全分析模块中，设置一个备自投模型，在所述的在线静态安全分析模块对预想故障扫描中，增加备自投动作分析功能，实现备自投动作之后的N‑1扫描，对备自投动作后的潮流进行计算，并基于分析结果生成事故预想文本；所述的潮流确定方法，采用备自投功能嵌入潮流计算的方式，提升了原先潮流计算的准确性，使计算结果更能反映真实电网的潮流分布情况，对调度员而言更具有实用和参考价值；实现了重要电力用户的供电连续性分析；实现了调度员事故预想支持功能。
摘要（英）：

The invention discloses a power flow determining method in a static safety analysis system in view of the operation of an automatic switching device of a standby power supply and belongs to the field of control. The method is characterized by setting an automatic switching device of standby power supply model in an online static safety analysis module; in the scanning of preconceived faults in the online static safety analysis module, adding an analyzing function of the operation of the automatic switching device of the standby power supply, achieving N-1 scanning after the operation of the automatic switching device of the standby power supply, computing the power flow after the operation of the automatic switching device of standby power supply and generating an accident preconceived text based on an analyzed result. By using a manner embedding power flow computation into the function of the automatic switching device of the standby power supply, the power flow determining method improves the accuracy of original power flow computation, enables a computed result to more reflect a real power flow distribution state of a power grid, has practical and reference values to dispatchers, achieves power supply continuity analysis for important electric power users, and achieves a dispatcher accident preconceive support function.
