水电站设计中的水轮机选型研究

Study on Hydraulic Turbine Selection in Hydropower Plant Design

摘要:

针对传统的水轮机选型方法难以充分满足水电站在不同运行条件下的需求，以某水电站为例开展了水轮机选型研究。首先，依据该水电站的基础数据进行了对比分析，初步提出了几种机组选型的方案；然后，针对所提方案在水轮机型式、型号和数量等方面进行详细的对比，综合考虑了经济性、维护便利性以及长期运行适应性等多方面因素，确定了最符合该水电站需求的机组选型方案。

Abstract:

Traditional hydraulic turbine selection methods struggle to fully meet the requirements of hydropower stations under varying operating conditions, so the hydraulic turbine selection is studied taking a certain hydropower station for example. Firstly, a comparative analysis based on the basic data of this hydropower station is carried out, and several schemes for unit selection are preliminarily proposed. And then, a detailed comparisons are carried out in terms of type, model and quantity. Finally, the most suitable unit selection scheme for this hydropower station is determined after comprehensively considering economic efficiency, maintenance convenience, and long-term operational adaptability.
