abstract
The application of the Monte Carlo method to the reliability analysis of emergency and standby power systems is discussed. A relatively small system consisting of two standby generators and one uninterruptible power supply (UPS) was used for illustrating the method. The reliability indices of an actual physical system is estimated by collecting data on the occurrence of failures and the durations of the repair. The Monte Carlo method mimics the failure and repair history of the components and the system by using the probability distributions of the component state durations. Monte Carlo simulations are flexible for incorporating dependent failures and yields the probability distribution of indices in addition to estimating mean values.
