Data reconciliation for sensor fault monitoring
Data reconciliation method is used to improve sensor fault detection, identification and data rebuilding for a high pressure feedwater heater and extraction steam pipe system in a 1 000 MW coal-ired power generation unit. The dominant factor modeling method is used to build the characteristic constraint relationships between the parameters. A case study shows that this method can efficiently detect, identify and rebuild data after sensor faults with an average relative error in the rebuilt data of 2.42%.
