The invention provides a method for improving the water energy utilization efficiency of a radial flow hydropower station. A water storage pool is built near a pressure front pool, so that temporary storage of power generation abandoned water is realized; a control device is arranged; and the control device can judge and control the start and stop of a water turbine generator set and a water pumping device according to the water level of the water storage pool and the water level of the pressure front pool, so that the energy loss of the abandoned water can be prevented, and the water energy utilization effect of the radial flow hydropower station is improved. 本发明提供一种径流式水电站提高水能利用效率的方法，通过在压力前池附近修建储水池，实现对发电弃水的临时储存，设置控制装置，该控制装置可以根据储水池水位、压力前池水位，进行判断并控制水轮发电机组及抽水装置的启停，从而可以避免弃水的能量损耗，提高径流式水电站的水能利用效果。
