摘　　要：概率安全性与概率充裕性评估是组合电力系统可靠性研究的两个方面。由于建模的复杂性和巨大的计算量,二者在过去一直是分开研究的,这样造成所得的两类指标缺乏可比性和统一性。本文将二者协调统一在同一框架内,提出了一整套综合评估风险指标,建立了完整的基于序贯蒙特卡罗仿真的发输电合成系统可靠性综合评估新体系。算法结合自组织映射网络和合并相同系统状态加速计算技术,并在安全性评估中考虑了不对称故障等多种故障模式对可靠性指标的影响。对IEEE标准可靠性测试系统进行计算分析,结果表明所提算法可行有效。Reliability of composite power system has been traditionally divided into two separate components , namely , security and adequacy .Therefore , the two obtained sets of reliability indices are incomparable and nonuni-form.This paper presents new comprehensive framework of algorithm and a set of indices based on sequential Monte-Carlo simulation approach .It is shown that the proposed new integrated model combined with self organizing map （ SOM） neural network and sampled states absorption technology results in a significant reduction in the com -putational effort required to compute reliability indices .All fault types and performance of protection scheme are considered in the new model that can reflect the stochastic nature of power system behavior accurately .The validity of the developed integrated algorithm is shown by numerical results of the IEEE-RTS test system .
