摘　　要：根据660MW超超临界机组特点以及国内外给水泵的加工制造情况,分析了100%容量汽动给水泵、2×50%容量汽动给水泵及100%容量主机驱动给水泵等3种方案的优点及存在的问题,并对各方案进行了技术经济分析。分析结果表明,100%容量主机驱动给水泵方案具有优势,可供同类机组设计参考。According to the features of 660 MW ultra super-critical units and the manufacturing situation of domestic feedwater pump, the advantages, disadvantages and the problems of three schemes are analyzed for 100% or 2x50% capacity turbine-driven and 100% capacity main steam turbine driven feedwater pump. By analyzing the technical and economic factors of three schemes, it is found that the scheme of 100% capacity host-driven pump is optimal, providing references for similar units design.
