Abstract
In order to solve the problem that the calculated discharge is larger than the measured discharge during the opening of the spillway gate of Nierji Reservoir,the paper analyzes the historical discharge data,and aims at the fast velocity and unstable flow pattern downstream of the spillway gate and the unstable flow pattern at the tail of the generator set,which makes it difficult to carry out flow measurement.A remote control unmanned ship carrying M9 type ADCP is used to measure the flow in the inlet channel upstream of the spillway to grasp the accurate discharge volume.By comparing the measured discharge with the calculated discharge,the random uncertainty under different parameters is analyzed and the optimal discharge formula parameters are obtained by modifying the discharge formula parameters.The optimal parameters are used to calculate the discharge flow,and according to the requirements of the specification,the symbol,the conformance line and the deviation are tested.The results meet the requirements.关键词
