Study on initial control strategy of water conveyance dispatch of Middle Route Project of South-to-North Water Diversion

The main line of Middle Route Project(MRP) of S-N Water Diversion has 61 controlling gates for the water diversion.According to the change of inflow and outflow and volume in the initial and terminal stages,the variation of discharge volume in the canals during the dispatching process can be divided into 4 cases,namely,gate close and water filling,gate close and water discharging,gate open and water filling,gate open and water discharging.The control strategy is made according to the 4 operations respectively.The starting and ending time of the flow adjustment of each controlling gate are determined,so that the initial control strategy of water conveyance and dispatch of MRP is developed,which meets the safety requirement.
