A small power plant is equipped with two identical generators in a cold standby system configuration. Hence, the standby generator starts working as soon as the active generator fails. The assumptions are that there are no interruptions between switches and that the switching system is 100% reliable. Each generator follows an exponential life distribution with a failure rate (lambda) of 3.6 × 10<sup>-5</sup> failures per hour. The reliability of the power plant at 5000 hours and the mean time to failure (MMTF) | A small power plant is equipped with two identical generators in a cold standby system configuration.
