目前中国水电机组的几个主要问题

Main problems of generating units in current China

国内特大型混流式水轮发电机组发展迅速,其水力稳定性问题已引起各方高度关注;转轮散件运输、现场 组焊方案的应用,低水头段宜首先考虑灯泡贯流式机组;大容量、高水头冲击式水轮机设计制造技术亟待提高。

With more and more waterpower resources exploited in the 21st century, there exist some problems regarding generating units, i. e. oversize Francis turbines are developed quickly in China, it has aroused high attention of various parties concerned to the hydraulic stability. The plan is put in practice that runners are taken apart to be transported and be combined in the workshop. The bulb turbine shall be firstly considered in the sections of low water head. The design and manufacture technologies of Pelton turbines that are applied to large capability and high head are desiderated to be improved.
