Title: Operational reliability evaluation of generating system considering ageing failure

The generating unit's ageing failure is taken into account in the paper. The repairable failure unavailability and the ageing failure unavailability are deduced from the unified definition of unavailability, and the forced outage model is obtained by using the theory of multiple failure competing risk failure. The selections of formula for computing unavailability in the reliability evaluation of different cycles are discussed. And they are applied to operational reliability evaluation of generating system, which is based on daily generation scheduling. Simulation analyses are given to indicate the effectiveness of the method. The methods and conclusions can be used in operational reliability evaluation of composite generation and transmission system, and also can be applied into operational reliability evaluation of generating system including wind energy and solar energy.Read More
