梯级水库群泄洪设施联合调控研究

Flood disaster is one of the most serious natural disasters in China, flood control of reservoirs is an important means to effectively avoid or mitigate flood disasters. Currently, flood control dispatching of reservoirs mainly uses optimization algorithm to obtain the optimal dispatching decision-making scheme, rarely considering the operation control of reservoir flood discharge facilities, which often leads to the deviation of the actual flood dispatching results from the optimal dispatching results. In this paper, by studying the digitalization of cascade reservoirs flood discharge facilities, the database of flood discharge facilities using is established, and combining with the joint flood control model of cascade reservoirs, the joint control strategy of cascade reservoirs flood discharge facilities is studied. Taking the joint operation of cascade reservoirs flood discharge facilities in the lower reaches of Yalong River as an example, the discharge process of optimal dispatching scheme is more uniform than that of conventional dispatching, which greatly reduces the peak flow. At the same time, the total number of cascade reservoirs flood discharge facilities changes in the optimal dispatching scheme is significantly less than that of conventional dispatching, and the frequency of flood discharge facilities combination scheme adjustment is significantly reduced. The research results have important theoretical significance and engineering practical value for promoting the refinement and intellectualization of cascade reservoirs flood control optimal operation to the operation control of flood discharge facilities.
