500MW冲击式水轮发电机组设计制造可行性研究

Feasibility study on design and manufacturing of 500 MW Pelton turbine generator unit

500 MW冲击式水轮发电机组超出了国内外现有冲击式机组单机容量应用实例范围,其核心部件的设计制造难度较大,为了研究其设计制造可行性,利用统计分析、数值模拟计算、模型试验等方法,对机组设计、水轮机核心部件制造、发电机高海拔防电晕结构等方面进行创新研究。研究结果表明:扎拉水电站500 MW冲击式机组的设计制造不存在制约性因素,可立足于国内自主完成。研究成果可为增强中国水电行业装备制造能力以及高水头水电站开发提供参考。

The 500 MW Pelton turbine generator unit exceeds unit capacity application examples of existing Pelton units both domestically and internationally.There are many difficulties in the design and manufacturing of the core components.In order to study the feasibility of its design and manufacturing,it is studied from the aspects of unit design,core component manufacturing of turbine,and high-altitude anti corona structures of generators by utilizing methods such as statistical analysis,numerical simulation calculations,and model experiments.The research results indicated that there was no restrictive conditions in the design and manufacturing of the 500 MW Pelton turbine gen-erator unit of Zhala Hydropower Station,and it can be independently completed domestically.The research results can enhance the equipment manufacturing capacity of China's hydropower industry and provide a successful experi-ence and demonstration role for the development of high head hydropower stations in China.
