Control Regulation Calculation for Basin Flood:Configuration Coupling Technique and Application

In the aim of quickly responding to the uncertain demand of calculating basin flood control and regulation, object modeling is carried out for basin flood control system. The complex flood control tasks are decomposed into relatively independent model algorithm components. The dynamic adaptation between flood control objects and model components under different flood control scenarios is studied. A configuration coupling method for calculating multi-type flood control is proposed. In view of the flood control system of the upper Yangtze River, the method is applied to the comprehensive analysis of reservoir storage and river flood discharge through dynamic coupling calculation integrating flood dispatching, backwater simulation and flood evolution in channel. The operational response speed is greatly improved. This method is flexible in task configuration, strong in adaptability and boasts high degree of reuse, hence would be playing an important supporting role in the intelligent control regulation analysis and consultation decision judgment of basin flood.
