|
Abstract:
汛期洪水资源利用一直是我国水库及水电站运行的研究热点，由于洪水形态各异、洪水过程难以刻画等难题，生产实际中洪水优化调度增发电量缺少有效的计算方法。本文通过运用洪前预泄腾库、洪中汛限水位动态控制、洪后拦蓄洪尾技术，建立了洪水优化调度实施全过程模型，将场次洪水过程分为洪前、洪中、洪后三个阶段计算理论发电量。结合实际工程案例说明了方法的可操作性和应用效果，对促进提高洪水优化调度水平有重要的指导和借鉴意义。
The utilization of flood resources in flood season has always been a research hotspot in the reservoirs or hydropower plants operation in China. Due to the flood with the characteristic of variable patterns and difficult description, there are few effective and practical methods for the calculation of increasing power generation. In this paper, the whole process model of flood optimal operation is established by utilizing flood discharge in advance, dynamic control of limited water level in middle flood process and storing flood tailwater. The stage flood process can be divided into three stages: pre-flood, mid-flood and post-flood event to calculate the theoretical power generation. The maneuverability and effectiveness of the model are verified with practical cases, which has important guidance and reference significance for improving the hydropower scheduling plan.
