柬埔寨达岱水电站导流洞下闸蓄水方案分析

Analysis of Water Storage Scheme for Closing the Diversion Tunnel of Tatay Hydropower Station in Cambodia

达岱河水电站布置2条导流洞,分别位于干流TATAY河和支流KEP河,进口高程相差26m,通过库区连通明渠将干支流库区连通。研究导流洞下闸蓄水方案,确定合理的导流洞下闸方案、下闸时间,使得水库蓄水风险控制在合理的范围内,实现工程按期投产发电。

Tatay Hydropower Station is designed with two diversion tunnels, which are respectively located in the TATAY River and the tributary KEP River. The elevation difference between two inlets is 26 m and an open channel is arranged in the reservoir area to connect the TATAY River and the KEP River reservoir area. The gate closing and water storage scheme is studied to determine the reasonable gate closing scheme and time, so that the reservoir impoundment risk is controlled within a reasonable range and the power station will be put into operation on schedule.
