Description

TECHNICAL FIELD

[0002] Compressed gas energy storage has the advantages of large scale, low cost, clean and pollution-free, and is considered as one of the most potential large-scale energy storage technologies. In a large-capacity energy storage system, how to solve the underground gas storage technology is the key to the safe, stable and economic operation of the energy storage system. Compared with salt cavern gas storage and ground storage tank gas storage, underground gas storage has the advantages of large capacity, strong economy and no regional restrictions, which is an ideal gas storage technology for compressed gas energy storage system.

[0003] In the underground gas storage, the most critical is to maintain the long-term, safe and stable storage of the gas storage working medium in the gas storage, which requires the gas storage to have good sealing, mechanical stability and long service life. However, the periodic compression and expansion behavior of the gas storage working medium affects the structure and material strength of the gas storage channel: on the one hand, the pressure change of the gas storage working medium will directly apply alternating stress to the pipe wall; on the other hand, the increase of the internal energy of the working medium will cause uneven temperature distribution of the pipe wall, resulting in local thermal stress. Therefore, in addition to further developing low-cost gas storage sealing technology, how to measure the flow and heat exchange behavior of the gas storage working medium in the gas storage and even the entire gas storage system is the key to ensuring the controllability of the system, maintaining the stable operation of the system and ensuring the safety production.

[0058] 5) The stored gas working medium enters the preheating section, and the temperature of the fluid before entering the experimental section is adjusted by controlling the current of the power supply (which is the first heating power supply);

[0059] 6) The electromagnetic three-way valve is used to adjust the direction of the stored gas working medium, which can choose to close the circulating pipeline or exhaust to empty the system pipeline gas;

[0060] 7) The stored gas working medium flows through the mass flow meter to measure the mass flow rate;

[0061] 8) The stored gas working medium flows through the pressure sensor and the differential pressure sensor (i.e. differential pressure gauge) to record the inlet pressure before entering the experimental section and the pressure drop after passing through the experimental section;

[0062] 9) The armored thermocouple arranged at the inlet of the experimental section measures the inlet temperature of the fluid in the experimental section;

[0063] 10) The stored gas working medium is heated in the experimental section, the heat flux density is controlled by adjusting the current of the power supply (which is the second heating power supply), and the temperature of the fluid and the strain of the solid pipeline are measured by the sensor (i.e. thermocouple and strain gauge) to obtain the heat flow and solid characteristics of the stored gas working medium;

[0064] 11) After the stored gas working medium flows out of the experimental section, the armored thermocouple at the outlet of the experimental section measures the outlet temperature of the fluid in the experimental section;

[0065] 12) The high temperature stored gas working medium enters the cooling section to cool down to room temperature;

[0066] 13) After flowing through the back pressure valve, it returns to the storage tank to complete the circulation process, and the whole process forms a closed circulation loop.
