Abstract
In order to reduce the probability of unit non-stop caused by factors such as control loop interference, open contact misoperation and low cable insulation, and to narrow the scope of system misoperation, This paper starts with the analysis of typical faults of control systems in recent years in thermal power plants, combines with the daily emergency response operation habits of operators, optimizes and adjusts the control strategy, and designs the “robbing control logic” module, which replaces the emergency operation of the operators and solves the misoperation caused by the control system abnormality, and realizes that it will not lead to the occurrence of accidents or the expansion of the range of accidents under the conditions of misoperation, so as to enhance the attribute of the control system’s intrinsic safety, and to provide references for the development of the control system’s intrinsic safety.
