Description

Technical Field

[0001] This utility model belongs to the field of energy storage and power generation technology, and relates to a power regulation device system for hydraulic compressed air energy storage. Background Technology

[0002] Currently, the energy storage field mainly includes battery energy storage, compressed air energy storage, and pumped storage energy storage. Among them, battery energy storage is relatively flexible in scale and mainly stores electrical energy. Compressed air energy storage converts electrical energy into physical mechanical energy, while pumped storage energy storage utilizes gravity based on the elevation difference of the site. With technological advancements, compressed air energy storage technology, due to its high stability and large capacity, has been continuously innovated and is widely used in various energy storage and release sites.

[0003] The existing technical solution discloses a compressed air energy storage and power generation device, in which an electric motor is connected to an air compressor unit, the air compressor unit is sequentially connected to a cooler, an air storage tank, a heating device, and a turbine expander unit, the turbine expander unit is connected to a generator, and the outlet of the air compressor unit is connected to the cooler through a first pipeline. The compressed air energy storage and power generation device also includes a pressure measuring device and a shut-off valve installed on the first pipeline. The pressure measuring device is installed at the outlet of the air compressor unit, and a booster pipeline is connected in parallel at both ends of the shut-off valve. A booster baffle and a booster device are installed on the booster pipeline. It makes full use of off-peak electricity, abandoned electricity, and other electrical energy, and can compress air to the maximum pressure that the air storage tank can withstand, so that the compressed air can expand better to generate electricity.

[0004] The existing technical solution discloses an energy storage distributed utilization system based on an industrial compressed air system, including an air pressurization system with an air storage device. The air pressurization system has an air storage device, which is connected to a first compressed air utilization system, a second compressed air utilization system, and a third compressed air utilization system. Each of the first to third compressed air utilization systems includes a heater, an expander, a cold energy heat exchanger, and a compressed air storage tank. In this way, the cold energy heat exchanger is used to exchange heat with the low-pressure gas after energy release for power generation, so as to produce cold energy to supply cooling for industrial users and even buildings in the surrounding area, reducing the peak load on the power grid. At the same time, with the setting of the three compressed air utilization systems, low-pressure gas with different pressure values ​​is stored, so that it can be distributed to the required compressed gas with different pressure values ​​for energy release and power generation again.

[0005] However, in existing compressed air energy storage systems, the expansion pressure gradually decreases during the expansion process, eventually approaching atmospheric pressure. This pressure drop causes a decrease in the pressure of the air entering the air turbine or the water flow into the water turbine, resulting in fluctuations in the speed of mechanical equipment and reduced power output, which are detrimental to energy utilization. Therefore, it is necessary to improve compressed air energy storage systems to enhance their power generation efficiency and address the issue of unstable power output. Utility Model Content

Thus, features defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0031] It should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "set," "connected," and "linked" should be interpreted broadly.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0032] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0036] It should be noted that in this invention, by adjusting the flow rate of compressed air and stabilizing the output pressure of compressed air, a smoother driving force can be input to the water tank, achieving the first stage of source regulation. By adjusting the amount of water entering the turbine, the output power of the turbine can be dynamically adjusted, stabilizing the generator's power output. The frequency converter rectifier 8 can stabilize the speed of the generator and turbine, and also rectify the generated current.

Atomized spraying can be selected, which can enhance the heat exchange between water and air. During energy storage, it can fully absorb the heat generated by air compression, and during energy release, it can release the heat into the air in a timely manner, thereby maintaining a constant air temperature and solving the problem of automatic energy storage and release based on the process of air expansion releasing heat and compression absorbing heat.

The tank body is usually made of high-strength metal (such as carbon steel, aluminum alloy or stainless steel) or composite material (carbon fiber winding), and must withstand high pressure (common working pressure 15-30MPa, or even higher); valves and interfaces can control the filling and releasing of gas and must have a leak-proof design; safety devices include pressure relief valves, rupture discs, etc., to prevent overpressure explosions; other accessories include pressure gauges, temperature sensors, transportation protection devices (such as shock-absorbing rings), etc.

[0047] It should be noted that the sealed water tank in this utility model can be a sealed container for storing liquids.

As the pressure in the gas storage container 2 decreases to the pressure set value, the hydroelectric power generation device 12 stops. The pressure of the water flow entering the water turbine is adjusted by the regulating valve set on the water turbine or pipeline. As the pressure decreases, the opening of the regulating valve is gradually increased until it reaches the maximum to stabilize the output power of the water turbine.
