Analysis of reliability growth model of domestic large thermal power unit

In this paper propose a method for determining the reliability parameters of repairable large thermal power units. The Weibull distribution model is applied to estimate the reliability parameters of Chinese-built 300 and 600-MW thermal power units. An analysis of both the FEMA fault and reliability growth models for the two thermal power units, is conducted to reveal the relationship between the increase in reliability and design improvements made after the elimination of defects. In addition, we compare the Chinese and American reliability growth models.
