生态流量水电站水轮发电机组选型中应注意的几个问题

摘要

As the relative constant discharge of ecological power station, the selection of turbine-generator is different to conventional hydropower project. The selections on ecological flow, installed capacity and number of units, runner diameter of turbine and generator capacity for ecological power station are summarized herein. The practices in three ecological power stations show that the selections are practical.%针对生态流量水电站下泄生态流量相对恒定的特点,对水轮发电机组选型中的几个问题,如生态流量的选取、水电站装机容量及机组台数选取、水轮机转轮直径的选择、发电机容量的确定等,进行了分析总结,并在3个生态流量水电站中进行了实践应用,效果良好.
