大型海上交流风电场内部拓扑优化设计

Optimal Design of Internal Topology for High Power AC Offshore Wind Farms

海上交流风电场的内部汇集网拓扑结构存在多种方式。介绍了评估不同拓扑结构的经济技术指标。在此基础上,以丹麦的Horns Rev海上风电场为例,给出了各种拓扑结构以及一种推荐的拓扑结构,并针对内部损耗、经济性、可靠性等各项指标,分别进行定量分析。分析比较结果表明:文中给出的Horns Rev海上风电场推荐拓扑综合性能更优,更具有合理性。

There are various topological structures for internal collection grid of AC offshore wind farms.Techno-economical indices to assess different topological structures are presented.On this basis taking the Horns Rev offshore wind farm in Denmark as an example,various topological structures and a recommended topological structure are given,and quantitative analysis on such indices as internal loss,economy and reliability are performed respectively.Analysis results show that the combination property of the recommended topological structure for Horns Rev offshore wind farm is more reasonable and is better than other topological structures.
