摘　　要：针对在发输电可靠性分析中故障频率和持续时间指标计算量太大的问题，提出了基于解析模型和非序贯蒙特卡罗仿真相结合的新算法，并分析了在大型实际系统计算中由于抽样次数限制和系统固有特性使结果出现误差的原因，继而给出了频率指标的上下界。通过一实际系统的分析计算，证明了理论分析的正确性以及所述算法的有效性及实用价值。In order to decrease the amount of computation in the analysis of frequency and duration indices for composite generation and transmission system,this paper proposes a new algorithm based on combined analytical model and nonsequential Monte-Carlo simulation.The causes of calculation errors in the large practical power systems,i.e.inherent characteristics of system and limitation of sampling are analyzed.The upper and lower bounds of the frequency index are presented. At last,this paper verifies the correctness and effectiveness of the proposed method by a practical power system.
