Definition,calculation,and monitoring of leakage rate in underground lined rock caverns for compressed air energy storage
摘要
Abstract
Ensuring high sealing performance and effectively controlling gas leakage in underground lined rock caverns for compressed air energy storage(CAES)are crucial for improving energy conversion efficiency.To accurately assess gas leakage,the leakage rate is first defined as the ratio of the gas mass leaked per unit time to the initial gas mass in the storage cavern.A calculation method for the leakage rate is then proposed,based on the gas state equation and real-time monitoring data.To achieve real-time monitoring,a comprehensive system comprising pipeline monitoring,in-cavern monitoring,and data processing modules is designed to continuously collect and process data.Finally,the method is validated by comparison with computational fluid dynamics simulations and applied in a pilot-scale model test.The results indicate that the proposed calculation method exhibits high reliability within a small margin of error and can accurately determine the real-time leakage rate of the storage cavern.Moreover,both the calculation method and the monitoring system have been successfully applied in the pilot-scale model test,demonstrating their effectiveness in practical operation.This research can provide on theoretical basis for improving the sealing performance of gas storage.关键词
