State Monitoring and Fault Diagnosis of Chemical Instrumentation for Power Plants
With the increasing level of automation in power systems,chemical instrumentation plays an increasingly important role in power plants,and its stable and reliable operation is crucial for ensuring safe and economical production.However,instrumentation also faces various fault risks,and the occurrence of faults will have serious consequences.This paper systematically expounds on the relevant theories and methods for state monitoring and fault diagnosis of chemical instrumentation in power plants.Firstly,the classification and application fields of chemical instrumentation are introduced,and the common fault modes and influencing factors are analyzed.Then,the model-based,knowledge-based,and data-driven fault diagnosis methods are discussed in detail,and the overall design framework of the fault diagnosis system is explored.Finally,the application of cutting-edge technologies such as big data analysis,intelligent diagnosis,and predictive maintenance is prospected.This research is of great significance for improving the reliability and safety of chemical instrumentation.
