Method for generating power by using stored potential energy

Abstract

A method for generating power by using stored potential energy comprises a method for generating the power by using potential energy stored in an air-raid shelter. According to the method for generating power by using the stored potential energy, gas compression equipment sucks and compresses gases; the gases are stored in the air-raid shelter by a heat energy storing device; the air-raid shelter exhausts the compressed gas for generating power; and the compressed gases pass through the heat energy storing device and then generates power by a turbine generator. According to the method for generating the power by using the potential energy stored in the air-raid shelter, a pipeline is arranged between the air-raid shelter with different heights and the liquid storing device; a water pump and a water turbine are arranged on the pipeline; the water pump pumps low-level stored water to the inside of a high-level water storing container; high-level stored water is drained to the inside of a low-level storing container; and gravity potential energy of the high-level stored water is converted into kinetic energy of the water turbine for generating power. According to the method disclosed by the invention, the air-raid shelter is used as the potential energy storing container, and thus the leakage-preventing construction cost is reduced; the gas compression equipment and the water pump are driven by adopting instable energy sources, and thus the utilization efficiency of the instable energy sources is increased and the phenomenon of wind omitted from wind and power is reduced; the cost of power generation is saved; and the method can be used in regions where natural gas is in shortage or regions where water resources are in shortage.

Description

technical field [0001] The invention relates to a method for generating electricity, in particular to a method for storing potential energy to generate electricity. Background technique [0002] As renewable energy, wind energy and solar energy have attracted the attention of various countries and invested a lot of funds for development and utilization, but the production of these two energy sources depends on the local weather, and people's ability to predict the weather is still very limited, so it is impossible to be effective. Harness existing wind and solar power. Due to the intermittent and fluctuating nature of energy collection, for a long time, it has been difficult to stably transmit the electric energy of this type of energy to more places that need electric energy through the grid. If we look at the power supply standard that can be delivered to the grid, the current utilization rate of wind power generation in China is only about 25%. In other words, most of t...
