AI Technical Summary
Existing technologies are insufficient for accurately testing and evaluating the charge and discharge performance of compressed air energy storage systems, especially the volume of underground salt caverns and other charge and discharge performance indicators, resulting in low measurement accuracy.
A charging and discharging performance testing system for compressed air energy storage system was designed, including a flow meter, a pressure transmitter, a temperature transmitter, and a power meter. Relevant parameters were collected through a data acquisition system, the actual volume of the salt cavern was calculated, and a charging and discharging performance testing and evaluation method was proposed.
It improves the testing accuracy of charge-discharge performance indicators such as salt cavern volume, provides a comprehensive evaluation of charge-discharge performance, and forms a normalized weighted comprehensive evaluation result.
