ABSTRACT

In order to reduce or avoid the adverse impact of the DCS system in the normal operation of the nuclear power plant on the operating state of the unit in the case of double AP failure, in this paper, the control logic is sorted out according to the signal characteristics of the DCS system after double AP failure in TianWan nuclear power plant, and the corresponding optimization measures for different types of controlled equipment are formulated. After theoretical analysis and simulation, the optimized logic can effectively reduce the adverse impact of double AP faults on the unit operation state.
