S-RC混合结构在大型风电场柔直户内换流站建筑中的应用

结合863大型风电场柔性直流送出的全户内换流站工程实例，介绍了全户内站工艺布置及荷载特点，充分利用钢结构及混凝土结构的各自特点进行复杂全户内站的结构设计。详细阐述了该全户内换流站采用S-RC混合结构体系的结构选型过程、结构布置特点及工艺优势，介绍了该全户内站结构整体计算及关键构件设计计算结果，并同全钢结构方案进行技术经济对比分析，展望了S-RC混合结构在全户内电力建筑中的应用前景和注意事项。为今后S-RC混合结构在复杂设计条件下的全户内电力建筑中的应用提供参考。

Application of S-RC Hybrid Structure in Indoor Substation of Large Wind Farms Transmission Through VSC HVDC

Through 863 large wind farms transmission using VSC HVDC technique project, steel-reinforcement concrete hybrid structure was introduced to be used in the indoor converter station structure design, according to its both advantage of steel structure and reinforced concrete structure. This paper gave the process how to select the structural form, the structure characteristics and its technology advantages; the structure integral calculation and key component design calculation results were shown in the design; after comparing with the whole steel structure form both in technical and economic aspect, prospects of using steel-reinforcement concrete hybrid structure in indoor substations and its key matters in design was discussed, which will be a good reference for the design of steel-reinforcement concrete hybrid structure in indoor substation in the future.
