Operation principle：
During energy storage, first flow control valve, the 3rd flow control valve, the 5th flow control valve are opened, and second flow controls
Valve, the 4th flow control valve are closed, and motor drives compressor bank work, and low-pressure gas is compressed into high pressure gas by compressor bank
Body, and by the first pipeline, gases at high pressure are sent in high-pressure gas container, meanwhile, water turbine set utilizes high-pressure gas container
The water of middle exclusion is generated electricity, and the liquid of exclusion is sent to external water source by pipeline, and keeps in high-pressure gas container
Low temperature constant voltage, working condition is sent to exterior terminal monitoring device by communicator in real time.In the process, by multiple pressure
Sensor and temperature sensor come in real-time monitoring high-pressure gas container and with the pipeline of high-pressure gas container UNICOM in pressure
And temperature, if gas pressure intensity in high-pressure gas container rises, control device pass through control first flow control valve reduce into
Enter the gas flow in high-pressure gas container, the 3rd flow control valve can also be controlled simultaneously to flow out in high-pressure gas container to increase
Amount of liquid, thus reducing gas pressure intensity；If gas pressure intensity in high-pressure gas container declines, control device passes through control the
Flow control valve, to increase the gas flow entering in high-pressure gas container, can also control the 3rd flow control valve to subtract simultaneously
The little amount of liquid flowing out in high-pressure gas container, thus increase gas pressure intensity；
During generating, second flow control valve, the 4th flow control valve, the 5th flow control valve are opened, and first flow controls
Valve, the 3rd flow control valve are closed, and the gases at high pressure in high-pressure gas container are sent to expansion unit by second pipe, expand
Gas expansion for doing work in unit, and generated electricity through electromotor, meanwhile, water pump assembly extracts the water injection in external water source
To in high-pressure gas container, and keep low temperature constant voltage in high-pressure gas container, working condition is sent to outer by communicator in real time
Portion's terminal monitoring equipment.In the process, held come real-time monitoring high-pressure gas by multiple pressure transducers and temperature sensor
In device and with the pipeline of high-pressure gas container UNICOM in pressure and temperature, if the gas pressure intensity in high-pressure gas container rises,
Then control device passes through to control second flow control valve to increase the gas flow flowing out in high-pressure gas container, can also control simultaneously
4th flow control valve come to reduce flow into high-pressure gas container in amount of liquid, thus reducing gas pressure intensity；If high-pressure gas hold
Gas pressure intensity in device declines, then control device is reduced in outflow high-pressure gas container by controlling second flow control valve
Gas flow, can also control the 4th flow control valve to increase the amount of liquid flowing in high-pressure gas container, thus increasing simultaneously
Gas pressure intensity；If the gas temperature in high-pressure gas container is too high, control device is made by controlling the 5th flow control valve
Cryogenic liquid enters the top of high-pressure gas container, and is flowed down by liquid distribution trough, increases gas liquid interfacial area, realizes gas-liquid
Caloic interacts, and realizes low temperature in high-pressure gas container, prevents temperature too high.If the gas temperature in high-pressure gas container is too high,
Then control device makes cryogenic liquid enter the top of high-pressure gas container by controlling the 5th flow control valve, and passes through liquid
Distributor flows down, and increases gas liquid interfacial area, realizes the interaction of gas-liquid caloic, realizes low temperature in high-pressure gas container, prevent temperature
Too high.
