摘　　要：基于序贯蒙特卡罗仿真方法,建立含风电场的发输电系统充裕度评估模型。计及输电线路故障和输电线路有功限制,建立考虑风向、尾流效应以及地形因素影响的风电场内各台机组捕获风速计算模型,并提出了新的关于风电场接入系统的可靠性指标。利用Matlab7编写了相应程序,对引入该模型的IEEE-RTS79系统进行可靠性评估。通过对比不同的接入方案,充分评估大规模风电场对发输电系统可靠性的影响。An adequacy assessment model of generation and transmission systems integrated with wind farms based on the sequential Monte-Carlo simulation approach was presented. In this model, an algorithm of wind speed captured by wind turbine generators in wind farms was established, which considers the randomicity of the wind directions, wake effects and terrain factor in wind farms, also the transmission network failure rate and capability constraints. New reliability indices about wind power integration in power systems were presented. Corresponding software was programmed in the Matlab 7. The calculation of the IEEE-RTS79 test system which wind farm model added was carried out. The reliability of generation and transmission systems integrated with large scale wind farms was evaluated by comparison of different integration solutions.
