The invention discloses a multifunctional testing system with an optimally designed water flow structure in front of a water inlet of a hydropower station. The multifunctional testing system comprisesa multifunctional simulation unit, a flow velocity monitoring device and a control platform. The multifunctional simulation unit comprises a reservoir area simulated basin, a trash rack, a stop log gate, a joining beam and a water inlet pipeline. The flow velocity monitoring device is used for monitoring the flow velocity of the top of the stop log gate, the flow velocity of the joining beam andthe flow velocity of the water inlet pipeline and sending the monitored data to the control platform. The control platform adjusts the distance between the trash rack and the stop log gate based on the monitored data. The invention further provides an operation method of the system. The reasonable design interval between the trash rack and the stop log gate is quantized, the water flow regime of the water inlet of the hydr
