Nuclear power station diversification accident monitoring and alarm device

Abstract

The present invention belongs to the nuclear power station accident monitoring technology field, and specially relates to a nuclear power station diversification accident monitoring and alarm device. Aiming at the defects in the prior art, the nuclear power station diversification accident monitoring and alarm device is provided to provide accident-grade alarm and state monitoring for a nuclear power station operator. The device comprises a monitoring terminal, a cabinet configured to execute alarm logic processing and state display, the alarm photon board of a computer protection system and the alarm photon board of an originating event; the cabinet configured to execute alarm logic processing and state display, the alarm photon board of the computer protection system and the alarm photon board of the originating event are connected through wires, and alarm facilitates of an external protection system is connected with a wire between the cabinet configured to execute alarm logic processing and state display and the alarm photon board of a computer protection system.

Description

technical field [0001] The invention belongs to the technical field of accident monitoring of nuclear power plants, and in particular relates to a diversified accident monitoring and alarm device for nuclear power plants. Background technique [0002] In a nuclear power plant, when a digital instrumentation and control system based on computer technology is adopted, the accident alarm of the nuclear power plant is generated by the digital reactor protection system based on computer technology after calculation and judgment according to the instrument measurement data, and displayed on the backup panel or other devices. Due to the inherent complexity of computer software itself, it is difficult or impossible to achieve "error-free" by using processors and software to achieve control and display. At the same time, software common-cause failures may also occur in computerized protection systems. If a common cause failure causes the failure of the I&C equipment of the reactor pr...

Problems solved by technology

However, in this display system, on the one hand, the unit status parameters are displayed on the screen of the process system, and different parameters may be distributed in different screens, which is not conducive to the operator's quick understanding; on the other hand, the main purpose of the display screen is to The operator provides the status of each equipment in the process system, and the non-accident handling-oriented accident screen

[0004] Some nuclear power plants also provide a system called "safety parameter display system" to display the safety-related parameters of the power plant, but these parameters are also a direct display of measured data and individual parameters, and no alarm is given from the perspective of accident judgment

[0005] Therefore, it is difficult for the operator to quickly judge the type of accident occurred by the unit through these parameters, and it is impossible to quickly take corresponding safety measures based on these parameter values
