摘　　要：针对大规模复杂电力系统进行预防性静态安全控制计算过程中,占用内存大、求解效率低的问题,提出一种基于补偿法的快速优化求解方法。通过分析该问题的优化机制,建立等效的求解模型,运用补偿法进行预想事故状态的快速分析计算,最后采用内点法求解问题模型,从而获得满足N-1安全准则的合理运行方式,防止N-1事故发生后系统越限故障的发生。在IEEE30、118、300节点系统以及S-1047仿真系统进行的测试表明,所提方法提高了大规模预防性静态安全控制的计算效率,可以快速准确地获得满足系统安全稳定运行要求的调整结果。Aiming at the huge memory occupation and low computation efficiency of the preventive static security control for large and complex power system,a fast optimized solution based on compensation method is proposed. The optimization mechanism of control calculation is analyzed,an equivalent model is established,the compensation method is applied in the fast analytic calculation of the postulated fault conditions,and the interior point method is adopted to solve the model,by which a rational operating mode satisfying the N-1 security criterion is obtained to prevent the system limit violation after N-1 contingency occurs. The tests for IEEE 30-,118-,300-bus systems and S-1047 system show that,the calculation efficiency of large scale preventive static security control is improved and the adjustment results satisfying the requirement of system secure and stable operation are rapidly and accurately obtained.
