This paper describes an integrated software developed for evaluating the reliability of power stations using the power system reliability theory and database technology. Capable of calculating the adequacy

security and economics indices of the main electrical scheme of a station based on the general n+2 State Markov Model

the software has realized the sensitivity analysis of reliability parameters. It also performs such functions as query

calculation

and analysis

which offers quantified information to decision-makers for designing

operating and planning a station. The characteristics

structural and functional design of the software are discussed. More importantly

the software has been applied extensively in practice

e.g.

the Three Gorges Station

the Xiluodu Station and the 500 kV Anshun Transformer Substation. The effectiveness of the software has been verified with good application results.
