[Abstract]:The calculation model of availability of complete thermal power units is established, and the calculation method of equivalent availability coefficient and equivalent forced outage rate of large thermal power units is put forward, and the reliability verification method of equivalent available coefficient design values is put forward. The reliability is verified by the statistical results of 45 platform annual operation data of 9 ultra-supercritical 1 000MW thermal power units in 4 thermal power plants. The statistical results of the correction coefficient of forced outage rate and the reduced output coefficient of the complete thermal power unit are given, as well as the calculation and verification examples of the design value of the equivalent available coefficient of the ultra-supercritical 1 000MW thermal power unit. The results show that the relative error range of the design value of the equivalent available coefficient is-0.55% 鈮，
