摘要
溢洪道作为水电站的一种重要泄洪建筑物,其工作闸门运行方式是保证安全可靠的重要因素,笔者以梨园水电站溢洪道为研究对象,详细介绍了其工作闸门的运行方式以及流激振动原型观测试验报告给出的健康状况评估结果,说明采用前期运行方式闸门结构可靠、运行稳定。最后对溢洪道工作闸门异地远方控制方式的实践与探索进行了阐述,并经汛期运行实践证明,在集控中心远控操作模式下溢洪道工作闸门运行稳定可靠,能够很好地适应基于流域集控运行及"无人值班、少人值守"运行管理模式的要求。
As an important flood discharge building of hydropower station,its working gate operation mode is an important factor to ensure safety and reliability.In this paper,the spillway of Liyuan Hydropower Station is taken as the research object,and the operation mode of its working gate and the health evaluation results given in the prototype observation and test report of flow-induced vibration are introduced in detail.It is shown that the gate structure with early operation mode is reliable and stable.Finally,the practice and exploration of remote control mode for spillway work gate are expounded,and the operation practice in flood season proves that the spillway work gate operates stably and reliably under the remote control mode of centralized control center,and can well meet the requirements of centralized control operation based on watershed and operation and management mode of“unmanned and few people on duty”.
