500MW级冲击式水轮机设计制造可行性研究

Feasibility Study on Design and Manufacture of 500MW Pelton Turbine

针对适用于西藏地区高水头条件的大型冲击式水电机组,从服务国家战略考虑,大唐集团开展某水电站单机容量从250MW优化到500MW级冲击式机组的科研攻坚。通过组织国内相关单位进行科技创新攻坚,从水轮机水力设计、不锈钢转轮锻件制造、转轮锻焊工艺等方面探索500MW级冲击式水轮机设计制造可行性,对于推动制造业的科技创新,突破技术短板,实现产业链整体升级具有重要作用。

For the large Pelton hydropower units suitable for high water head conditions in Tibet, from the perspective of serving the national strategy, Datang Group has carried out scientific research to optimize the single unit capacity of a hydropower station from 250MW to 500MW Pelton units. By organizing relevant domestic companies to tackle key problems in scientific and technological innovation, the feasibility of design and manufacturing of 500MW Pelton turbine is explored from the aspects of hydraulic design of hydraulic turbine, manufacturing of stainless steel runner forgings, runner forging and welding process, which plays an important role in promoting scientific and technological innovation in the manufacturing industry, breaking through technical weaknesses and realizing the overall upgrading of the industrial chain.
