考虑障碍区影响的海上风电场集电系统拓扑设计
摘要：对于海上风电场集电系统的优化设计,现有设计方法大部分只考虑了电缆和开关的合理配置,而没有充分考虑障碍区对拓扑设计的影响。为此,本文提出了一种考虑障碍区影响的海上风电场集电系统拓扑优化设计方法。采用GIS技术对障碍区进行图层化处理,并利用最小面积不定形包围盒法将障碍区表示为最小面积矩形包围盒。在此基础上,结合Dijkstra算法与Prim算法的优点可得求取避障路径的优化算法,再通过基于层次分析法且兼顾经济性和可靠性两个方面影响因素的模糊综合评价模型来比较海上风电场集电系统的拓扑方案,就可完成海上风电场集电系统的最优拓扑设计。最后的算例及分析验证了本文算法的可行性。
Abstract:For the optimal design of wind power collection system for offshore wind farms, only reasonable configuration of the cable and switch is considered in most of existing design methods, and the impact of obstacle area on topology design is not analyzed. In this paper, a concrete topology optimization method of wind power collection system for offshore wind farms is presented by considering the effects of obstacle area. The geographic information system technology is used to process figures of the obstacle area, and the obstacle area is described as the minimum area rectangle encasing box by using minimal area encasing box method. On this basis, the optimization algorithm combining the advantage of Dijkstra algorithm and Prim algorithm is used to gain the obstacle avoidance path. Then a fuzzy comprehensive evaluation model based on the analytic hierarchy process (AHP), in which the economic and reliability factors are considered, is constructed to compare the performance of the different topologies. In the end, the optimal topology design of wind power collection system for offshore wind farms can be obtained. Case studies demonstrate the feasibility of the proposed algorithm.
