基于水质达标的水电站最小下泄流量研究

Study of Minimum Water Release for Hydropower Station Based on Requirements of Water Quality

确定水电站坝下最小下泄流量、满足下游河流水质要求是水电站调度重要考虑因素。该文以青山水库水电站为例,以下游南苕溪汪家埠断面水质达标为目标,对坝下最小下泄流量的确定进行了研究分析,为管理部门提供决策依据。

A important factor of hydropower scheduling is to determine the minimum discharge of hydropower dam and meet the requirements of the downstream river water quality. The article takes hydropower station of Qingshan reservoir for example, aiming at up to the water quality standard of Wangjiabu section in the downstream of Nantiao creek, researches and analyzes how to confirm minimum drainage flow under the dam, providing the decision-making support to the management department.
