Constant-pressure water-gas compatible cabin power energy storage system

Abstract

The invention discloses a constant-pressure water-gas compatible cabin power energy storage system. The power energy storage system comprises a water-gas compatible cabin, a gas compressor unit, a water pump unit, a water reservoir and a water turbine, wherein a water draining port of the water turbine is used for providing ingoing water for the water reservoir; the water pump unit is used for pumping water from the water reservoir through a pipeline; an outlet of the gas compression unit is communicated with the water-gas compatible cabin through a valve and a pipeline; an outlet of the water-gas compatible cabin is communicated with the water turbine through a pipeline and a valve; and the water turbine drags a generator to generate power and output power energy. The power energy storage system is characterized by further comprising a steam boiler which is connected with the water-gas compatible cabin through a first intelligent valve and a steam conveying pipeline; one path of an outlet of the water pump unit is communicated with the lower part of the water-gas compatible cabin through a third intelligent valve and a pipeline; another path of the outlet of the water pump unit is communicated with the upper part of the water-gas compatible cabin through a second intelligent valve and a spraying pipe; and the three intelligent valves are controlled by a gas pressure stability control device.

Description

technical field [0001] The invention relates to a system for physical energy storage of electric energy, in particular to a system for realizing electric energy storage by utilizing a water-air coexistence chamber. Background technique [0002] Since last year, China has surpassed the United States to become the world's largest energy consumer. In the future, with China's rapid development, energy consumption will increase significantly. my country will bear more and more burdens in energy consumption, energy conservation and emission reduction Greater international pressure. [0003] At present, the mainstream trend of world energy development is undergoing major changes, and is gradually moving towards the road of abandoning nuclear power and hydropower. For example, Germany, the core country in Europe, has announced that it will abandon nuclear power in 2020, and other European countries have blown up expired hydropower stations; With energy utilization, gradually increas...
