[0002] Hydroelectric power generation in the prior art increases the potential energy of water by building dams. When water falls from a high place to a low place, the water turbine converts the potential energy of the water into mechanical energy, and the water turbine drives the generator to convert the mechanical energy into electrical energy, thereby Electricity is generated and transmitted through the grid, but the cost of storing electricity is relatively high. Therefore, during peak power consumption, hydro turbines and generators need to work at high loads, while during low peak power consumption, hydro turbines are not needed. Work with the generator at full load, and even require some units to stop working
However, since the water storage capacity of the reservoir is limited, when the water storage capacity of the reservoir exceeds a certain value, the water needs to be released, which in turn causes a waste of hydraulic potential energy

The invention relates to a hydraulic power potential energy comprehensive utilization system and belongs to the technical field of hydraulic power complementary energy reutilization. The hydraulic power potential energy comprehensive utilization system comprises a water turbine, a generator and an air compression system, wherein the water turbine converts hydraulic power potential energy to mechanical energy which drives a rotor of the generator to rotate; the generator converts the mechanical energy to electric energy, and the air compression system converts the hydraulic power potential energy to compressed air to store or transmit in a form of gaseous energy. The air compression system is capable of converting the hydraulic power potential energy into the gaseous energy which can be stored and transmitted in a long distance.
