摘要
介绍了交直流并联系统暂态稳定模型,分析了影响暂态稳定性的各种随机因素并提出了概率稳定性评估的定量指标。通过对扰动及系统响应的时序结构分析,提出了并行分解定理,从而建立起交直流并联系统概率稳定计算的并行分解Monte Carlo法。本文还通过算例说明了有关概念及方法的应用。
This paper presents a new method for the probabilistic stability evaluation of AC/DC power systems. The transient stability model is described and the stochastic factors having effects on the stability behaviors are analysed and modeled. A theorem governing the probabilistic relations among the occurences of different types of disturbances is derived. A method of parallel computation is oresented, which is based on Monte Carlo simulation. An illustrative example is also given to show the application of the concepts and method presented in this paper.
