Intelligent Fault Isolation of Control Valves in a Power Plant

In this paper fault happening for control valves in a power plant is considered. The method is implemented for boiler feed water valve and is extendable to boiler fuel valve and governor valve. Fault kind and location is determined using measurement of boiler state variables. In spite of robust controller design, it may be unable to handle these faults and restricts their effects. A fuzzy compensator does fault accommodation tasks prosperously with modification set-points to the controller. Fuzzy supervisor is implemented in a way which prompts simulation time related to the current implements. Simulation results show the effectiveness of the proposed methodology
