The Shahe Pumped Storage Power Project comprises two units of 50MW singlestorage reversible pumpturbine/motorgenerator. There are trashrack and emergency gate installed on the intake (outlet) of both upper reservoir and lower reservoir. According to flow characteristics in regard to a pumped storage power project, this paper analyzes the causes of failures of the trashracks in a few of pumped storage power projects constructed in the world. During the design of trashrack, some measures were taken in several aspects such as trashrack structure, shape of screen rack, connection of screen rack and cross beams, vibration control. These measures are as follows: enhancing design criterion, increasing the stiffness and intensity of trashrack, emphasizing quality control of welding lines, minimizing clearance between trashrack and trashrack slots. But in the design of trashrack for pumped storage power project, some criteria especially for dynamic calculations needs to be further studied.

江苏沙河抽水蓄能电站安装2台50MW的单级可逆式水泵水轮发电电动机组。上下库进(出)水口都设有拦污栅和事故检修闸门。在拦污栅选型设计时,分析了已建抽水蓄能电站拦污栅损坏的原因,从结构、栅条形状、栅条与横梁的连接以及强迫振动频率与构件自振频率的比值等方面都采取了一些有利的措施,如提高设计标准、增加栅体的整体刚度、强度,并重视连接焊缝的质量控制,减小栅体与栅糟的配合间隙等,收到了一定的效果。但目前抽水蓄能电站栏污栅的设计标准和结构计算尤其是动力计算标准是今后要进一步研究解决的课题。
