Accident monitor system for nuclear power unit and monitor method thereof

Abstract

The invention relates to an accident monitor system for a nuclear power unit and a monitor method thereof. The system comprises a state display device for displaying the system parameters and the equipment state of the entire nuclear power unit, wherein the state display device comprises a state monitor module, a parameter monitor module and an operation link module. The accident monitor system of the nuclear power unit and the monitor method thereof can effectively classify various complex information of the nuclear power unit to provide rapid and accurate system parameters and equipment state to operators together by using only one display device, thereby fully using the digitization characteristics. The possible control risk resulting from frequent switching of control frames due to the digitization can be obviated through continuous display of the important parameters and the important equipment state. Different supervision images can be achieved through reasonable links, and the rapid navigation among electronic program images can ensure smooth unit control so as to effectively reduce the work loads of the operators.

Description

technical field [0001] The invention relates to an accident monitoring system, more specifically, to an accident monitoring system and a monitoring method of a nuclear power unit. Background technique [0002] The control system of the nuclear power unit of the nuclear power plant is an important part of the nuclear power plant. The safe and reliable operation of the unit depends to a large extent on the performance level of the control system of the nuclear power unit. Whether the display interface of the control system is friendly is very important to the operators of the nuclear power plant. . At present, due to technological progress, newly-built nuclear power plants have begun to adopt a fully digital control system, which will improve and transplant the mature distributed control system (Distributed Control System, DCS) of conventional power plants, and fully apply it to conventional islands, BOP, and nuclear islands. It constitutes the control system of the nuclear p...

Problems solved by technology

[0006] 1. Since the operation step screen and the process operation screen are mixed and displayed on the same display device, and the process equipment can be controlled by controlling the process operation screen, the maintenance and modification of the operation steps and the process operation screen display device are inflexible and the cycle is long, which cannot meet the requirements During actual operation, it is required to modify or adjust the operation steps according to the specific situation; every time it is necessary to modify the software that directly interacts with the process equipment, which brings insecurity;

[0007] 2. Since the main operation steps and detailed operation steps are displayed on the same display device, and the main operation steps and detailed operation steps cannot be displayed at the same time, the operating personnel often lose their direction when performing complex operations and lose overall control over the unit status , prone to human error

Does not meet the requirements of existing accident procedures
