Abstract

The invention provides a first fault and actuator supervisory-integrated type security function monitoring system and method. The system comprises an actuator supervisory module used for acquiring the actuator supervisory information, a first fault module used for acquiring the first fault information, a security function overview module used for acquiring the security function overview information, and a display module used for displaying various types of information. According to the technical scheme of the invention, by adopting a security function overview display system, an operator can visually and comprehensively understand the condition of the power plant security function. Meanwhile, a security function indicator can be displayed at a fixed position according to a reasonable sequence, so that the operator can quickly identify a security function that is triggered. Only faulted actuators are displayed in the list manner in an actuator monitoring list, so that the number of pictures is reduced. Therefore, the operator is facilitated to quickly find out the reasons of faults. The actuator supervisory function, the first fault function and the security function are centralized to be completed in the same picture, so that the monitoring efficiency of the operator for the security function is improved.

Description

technical field [0001] The invention relates to the safety technical field of nuclear power plants, in particular to a safety function monitoring system and method integrating first failure and actuator supervision. Background technique [0002] In order to ensure nuclear safety, nuclear power plants are equipped with several safety functions. When the state of the power plant is abnormal, the relevant safety functions will be automatically activated to ensure that the power plant is in a controllable state and no nuclear safety accidents will occur. When the relevant safety function is triggered, it is necessary for the instrument and control system to notify the operator in time, and help the operator analyze the cause of the trigger of the safety function and monitor the execution of the safety action sequence. [0003] In the existing CPR1000 nuclear power plant, when the safety function action is triggered, the first fault detection function will be turned on, and the o...
