Abstract

Taking the regenerative system of a 600 MW supercritical coal-fired unit as an object of study and introducing the diagnosis model based on structural theory of thermo-economics, the fault indices of a failed component were calculated through thermodynamic simulation model. Based on the diagnosis model and adopting the "Memory" method, the fault source was located by separating the induced fault from the inherent fault. Results show that with features of simplicity, accuracy, and capability of locating the fault component merely by thermo-economic calculations under different boundary conditions, the model can be used as an effective tool for fault diagnosis of thermal systems.
