摘要
提出了一种基于快速开断模拟以及事故后有功无功综合调整优化模型的发输电组合系统可靠性评估交流潮流分析法。该快速开断模拟充分利用一阶开断事件的信息去模拟高阶开断事件,有效地提高了模拟速度;该优化模型应用同心松弛概念,线性增量约束,进行有功无功综合调整,满足了速度和精度的需要。本文以IEEE可靠性试验系统为例进行了计算,结果表明该算法精度高,与R.Billinton等人的方法速度相当。
An A. C. load flow analysis of the reliability evaluation of composite generation and transmission systems is presented on the basis of a fast outage simulation algorithm and an optimal model of active and reactive power adjustment after outage contingencies. The information of the first -level outage events is utilized for simulating higher -level outage events in the fast outage simulation algorithm ; the optimal model is satisfactory in speed and accuracy with the application of concentric relaxation and linear increment constraint on the comprehensive adjustment of active and reactive power. As an example. the IEEE Reliability Test System is tested and the results show that the method is accurate and well-matched in speed with the method studied by R. Bllinton, et al.
