摘要：
This paper studies reliability of power substation with parallel connected power transformers and its preventive maintenance strategy. The processes of transformers failure are modeled by Poisson processes with correlation. Representing by multi-Gaussian Copula function, the mathematical formula of reliability of three power transformers connected parallel is given, and the reliability of substation with preventive maintenance schedule is studied. By the mean of Monte Carlo simulation, the reliability of three power transformers parallel connected is calculated, and its preventive maintenance schedule is discussed. The research of the paper shows that the failure correlation of transformers is key factor to the preventive maintenance schedule.
