摘要 梨园水电站引水系统采用单管单机斜向进水,单机引用流量621.4m3/s,大流量,大管径.以不设置上游调压室为布置原则,比选了多种方案,经过布置方式、工程量、投资经济比较确定了推荐方案,并进行了有限元计算,确定了最终的布置方案。目前,梨园水电站已经投产发电,运行情况良好。 Liyuan Hydropower Station is the third cascade hydropower plant located on the middle reaches of the Jinsha River according to the planning of the Jinsha river development. Its water diversion system for power generation is characterized by large discharge, large pipe diameter, one pipe to one generating unit and oblique inflow without an upstream surge chamber. The utilizable discharge per unit is 621.4m3/s. The layout was proposed after a comparison made among a number of layout alternatives of the system in terms of arrangement, construction quantities and investment, and it was finalized through finite element calculation. At present Liyuan Hydropower Station has been under good commercial operation.
