海上风电场联合送出优化方案研究

Research on Offshore Wind Farm Optimization Scheme for Joint Delivery

[目的]结合我国广东地区海上风电场布置及典型送出方案,对两个300MW风电场联合送出的方案进行了探讨。[方法]在电气主接线、海缆选型、可靠性分析、海缆敷设与供货、可比投资等方面进行了分析比较。[结果]最终得出联合风场送出的优化方案,即设2座220kV海上升压站+1座陆上集控中心,其中1座升压站通过1回3×1000mm^2海缆接至另1座升压站GIS,汇流后再通过2回3×1000mm^2海缆一并送出至陆上集控中心。[结论]联合送出的优化方案可大大节省投资并减少用海面积,可为后续海上风电场电气设计提供参考。

[Introduction] According to the offshore wind farms layout and typical delivery scheme of Guangdong area,the paper discusses the two joint delivery schemes of 300 MW offshore wind farm.[Method] From the aspects of electrical single line diagram,submarined cable′s selection,reliability analysis,cable laying and supply,comparable investment and so on were compared.[Result] To provide an optimization for the joint delivery of offshore wind farm,setting two 220 kV offshore booster station and one onshore control center,one of the booster station connect to another with one 3×1 000mm^2 submarine cable,then sent out with two 3×1000mm^2 submarine cable to onshore control center.[Conclusion] The scheme of two joint delivery schemes of 300 MW offshore wind farm can save the investment and reduce the area of sea which offers reference for the prospective electrical design of offshore wind farm.
