摘要
提出电网控制中心安全预警和决策支持系统按时间、空间和对象等3个维度进行设计。在时间维上,将电网事故看做事件的发展过程,分析中考虑电网暂态、动态和稳态等状态变化;在空间维上,考虑电网调度管理体制的分层分区,电网分析应分解协调进行;在对象维上,既考虑功角稳定和电压稳定,又考虑安全和经济。文中描述了系统的总体设计框架和功能,论述了系统的特点,给出了部分计算结果。
An early warning and security countermeasure （EWSC） system is proposed in this paper. This EWSC system is designed according to three-dimension analysis. In time dimension, a contingency is considered as a time evolution process of a sequence of events and the analysis is done by transient, dynamic and steady states separately and comprehensively. In space dimension, hierarchical dispatch and control are considered and the decomposition and coordination between control centers are carried out in the network analysis of the EWSC system. In objective dimension, phase angle security vs voltage security and security vs economy, are all considered. Overall design of the EWSC system is given and the exclusive features of the system are described. Some extensive calculation results obtained by the EWSC system are reported.
