飞来峡水轮机选择若干问题的回顾

Review on Issues Relating to the Selection of Turbines for the Feilaixia Hydropower Station

飞来峡水利枢纽电站位于北江干流的中游，是一座典型的低水头径流式电站。枢纽以防洪为主，同时兼有航运、发电等综合利用的功能。电站水轮机的选择经历了立式轴流机组、国产灯泡贯流式机组及最终通过国际招标选用进口灯泡贯流式机组的过程。飞来峡水利枢纽已竣工发电，对水轮机选择的若干问题进行回顾和总结，并从中得出一些有益的启示，对提高灯泡贯流式机组的应用水平是十分必要的，对今后类似的低水头径流式电站的水轮机选择也具有一定的参考意义。

The Feilaixia Hydropower Station is located at the middle-stream of the North River and it is a typical low-head stream-flow hydroelectric plant. The Feilaixia project mainly aims at the flood-control. It also functions as navigation, electricity generation and other comprehensive utilization. The selection of turbines for this plant underwent through the selections of the vertical axial-flow turbine unit ,the national produced bulb tubular turbine unit ,and finally, the imported bulb tubular turbine unit was selected through the international competitive bidding. Now,The Feilaixia Hydropower Station is generating electricity. We may draw beneficial inspiration from the review and summary of those problems relating to the selection of the turbines ,which is necessary for raising the application level of the bulb tubular turbine unit. This works to a certain extent, will be of reference significance in future for selection of similar low-head stream-flow hydroelectric plants.
