Evaluation of reliability and M.T.T.F. of a power plant with the aid of Boolean function expansion algorithm

Abstract

In this paper, investigations have been carried out for the evaluation of reliability behaviour of a power plant with the aid of Boolean function expansion algorithm. The complex system under consideration consists of two power generators in a power house. The object of the system is to supply power from a power house (generated by generators) to critical consumers fed from an output main switch and, consequently, the reliability of the power supply has been calculated by considering that failure times for various components, viz. cables, generators and main switch boards, etc., follow arbitrary distribution. In particular, system mean time to failure (M.T.T.F.) has also been calculated for exponential failure time distribution. Some graphs have also been plotted to highlight the utility of the model.
