摘要
集电网络是海上风电场电气系统的重要组成部分,其拓扑结构的设计选取与海底电缆的路径和截面密切相关。针对集电网络常见的放射形、环形2种结构,以电缆成本最优为目标,建立经济性优化模型,采用单亲遗传算法(single parent genetic algorithm,SPGA)对模型进行求解,以实际案例对2类结构的经济性进行优化,从中选取2种最优结构作可靠性评估,结合经济性及可靠性的定量分析数据,给出了每种方案的各自适用范围,为大型海上风电场集电网络规划提供了有效的优化方法。
As an important component of offshore wind farm, the design of the topology of power collection network is closely related to the paths and cross sections of submarine cables. Based on two most common structures, namely the radial structure and the circle structure, and taking the minimum cable cost as the objective, an economic optimization model is established and solved by single parent genetic algorithm （SPGA）. The economy of the two kinds of structures is optimized by actual case, and then two optimal structures of them are chosen for reliability assessment. Combining with the data from quantitative analysis of economy and reliability, respective application scope of each structure is given
