Abstract :
As an important part of power plant, high press feed water system is responsible for providing water for boiler incessantly. In traditional maintenance strategy, replacement or inspection time is determined just according to overhaul or minimal maintenance standard items, the result is either maintenance cost increasing due to excessive maintenance or reliability decreasing due to deficient maintenance. For the problem, a frame of risk-based maintenance (RBM) decision is put forward, the expression method of failure effect and risk is determined, and the optimal maintenance interval of equipment in system is decided by using fault tree algorithm. Take the high press feed water system of a certain 300 MW unit as example, the maintenance decision is made. It is shown by the instance that this method is feasible and effective, and the decision result can be used as a support for maintenance plan.
