摘要
鉴于规划阶段对风电场运行可靠性评估的重要意义,以风电场的有功出力为研究对象,在分析风电场集电系统拓扑结构及元件可靠性模型的基础上,考虑了风速变化对系统可靠性指标的影响,设计了一种序贯蒙特卡洛法与深度优先路径搜索法相结合的风电场可靠性评估流程。通过算例分析比较了不同拓扑结构下风电场的可靠性指标,结果表明,相较于放射形拓扑,采用单边环形拓扑与双边环形拓扑结构的风电场等效停运率分别降低7.92%、7.79%,单边环形拓扑结构的可靠性最高,所建可靠性模型和评估方法有效可靠。
In view of the significance of the reliability evaluation of wind farm operation during the planning phase,taking the active power output of wind farms as the object study,based on the analysis of the topology structure and component reliability model of wind farm collection systems,considering the influence of wind speed changes on system reliability indicators,this paper designs a wind farm reliability evaluation process combining sequential Monte Carlo method and depth first path search method.Afterwards,the reliability indicators of wind farms under different topology structures are compared and analyzed through examples.The results show that comparing with the radial topology,the equivalent outage rates of wind farms using single-sided ring topology and double-sided ring topology are reduced by 7.92% and 7.79%,respectively.The reliability of single-sided ring topology is the highest,and the established reliability model and evaluation method are effectiveand reliable.
