地区电网故障驱动的静态安全分析系统的设计

Fault-driven Static Security System of Regional Power Grid

为了解决地区电网静态安全分析系统中待分析(预想)事故数目较多的不足,本文引入故障在线分析技术,采用其分析得到的(疑似)故障设备列表和变位开关列表作为输入,减少静态安全分析计算中(预想)事故的数目,加快其分析计算的速度。针对地区电网静态安全分析结果以列表展示的不足,引入风险评估算法,为电网安全性评分,给值班员一个电网安全性的量化概念。工程实践证明,所改进的系统缩小了计算范围和次数,降低了计算压力,提高了静态安全分析系统的工程实用性。

Traditionally, the static security analysis system of the regional power grid needs to process a large count of （expected） accidents. The on-line fault analysis system is established, which provides lists of （suspected） fault devices and related circuit breakers, reducing the calculation pressure of static security analysis, accelerating the calculation speed. Besides, the static security analysis system of the regional power grid usually displays final results as a table. The risk assessment system is developed, giving a mark for power grid security. The practice indicates that the improved system can reduce the calculation scope and times, reduce the pressure of computer calculation and improve the practicability of the static security analysis system.
