摘要

At present, the scheme adopted in inlet valve leak test of the expander in compressed air energy storage (CAES) power station and the test parameter are not definite, the leak test lacks the scientific demonstration, and there is no quantitative index of whether the inlet valve is tight. In order to estimate the leakage of inlet valve accurately and ensure the safe running of CAES power plant, through comparative analysis on the inlet valve tightness test method of steam turbine and gas turbine in thermal power and nuclear power, in combination with the structural dynamic characteristics of expander and its operation features, this paper puts forward the inlet valve leak test method of expander and its judgment basis, and compares the idling time data of different time periods to obtain the variation of CAES inlet valve leak test. The method introduces the expander speed as the judgment basis and quantifies the acceptable index of leak test, which makes the test more objective and operable, and ensures the safe and stable operation of expander.
