摘要
汛期运行水位是水库调节防洪和兴利矛盾的焦点所在,为实现水电站水库汛期发电效益最大化,假定入库径流预报误差服从均匀分布,建立了龟都府水电站水库汛期调度发电量最大模型,并计算不同汛期运行水位下的发电效益和防洪风险。算例分析结果表明,在现有预报水平下,建议水库汛期运行水位可提高0.2 m,可多发电384.87万kW·h,且水库防洪调度风险率在可控范围内。成果可为入库径流不确定条件下的水电站水库开展洪水资源化利用工作提供参考。
The operating water level during flood season is the focus of the conflict between reservoir flood control and its power generation benefit.In order to maximize the power generation benefit of Guidufu Hydropower Station during the flood season,the maximum power generation model during the flood season is established under the assumption that the inflow runoff forecast error is subject to uniform distribution,and the power generation benefits and the flood control risk probabilities of the station under different operating water levels are calculated.The results of case analysis show that,at current forecast level,the operating water level of reservoir during flood season can increased by 0.2 m,which can generate an additional electricity power of 3.8487 million kW·h,and the risk rate of reservoir flood control dispatching is within the controllable range.The results can provide references for the flood resource utilization under the condition of uncertain inflow runoff of hydropower stations.
