摘要: 随着海上风电场装机容量日益增加,风电场集电系统拓扑结构将成为影响海上风电场可靠性与经济性的关键因素,为此本文提出了风电场集电系统可靠性评估模型与经济性评估方法。考虑了集电系统内部电气元件的多重故障,采用分块枚举法,比较了风电场集电系统不同拓扑结构的可靠性,计算得到年电量不足期望值和系统等效可用率等可靠性指标以及不同拓扑结构下风场运行容量概率模型。并计及系统可靠性对经济性的影响,综合考虑一次投资成本和故障机会成本,计算得到不同拓扑结构的经济性指标。通过算例分析得到,单边环形拓扑结构的可靠性最高,链形拓扑结构的经济性最优。与以往评估集电系统拓扑结构可靠性与经济性的研究相比,本文考虑了电气元件的多重故障,得到了不同拓扑结构风场运行容量概率模型,评估结果准确合理,研究更具广泛意义。Abstract: With the growing installed capacity of offshore wind farm, the topology of wind power collection system for wind farms will become the key factor that affects the reliability and the economy of offshore wind farms, and the reliability and economy evaluation method of the wind power collection system for wind farms is proposed in this paper. Considering multiple failures of the electrical components in the wind power collection system, the reliability of different topological structures of the system is compared by using the block enumeration method, and such reliability indexes of the system as insufficient expected energy and equivalent availability of the system and the operation capacity probabilistic model of wind farm under different topologies are calculated. Furthermore, considering the impact of system reliability on economy, the once capitalized cost and failure opportunity cost are comprehensively analyzed, and economic indexes of different topologies are calculated. It can be analyzed from case that the reliability of the unilateral ring topology is the highest, and the topology of the radial topology is the most economical. Compared with the previous studies on the reliability and economy of topologies of wind power collection systems, the multiple failures of electrical components are considered in this paper, and the probability model of wind operation capacity under different topological structures is obtained. The evaluation results are accurate and reasonable, and the research has broader significance.
