Abstract

Control systems used in power plants consist of some control modules which are operated independently. A failure of control system mainly depends on a failure of control modules. So, it is important to estimate lifetimes of control modules in order to assess the reliability of control systems. In this paper, three methods for estimating lifetimes of control modules are presented and control modules' lifetimes of boiler control system used in a thermal power plant are estimated applying the three methods. Also, advantage and disadvantage of three methods are presented.
