Embodiment 1

[0030] The invention provides a nuclear power plant remote shutdown station system, such as figure 1 As shown: it includes a remote outage station 10, an operator workstation module 100 installed in the remote outage station 10, and a switching unit assembly 200 arranged inside and outside the remote outage station 10; the application refers to the remote outage station 10 It is set on the unconventional inspection and evacuation path of the safe plant to prevent irrelevant personnel from entering and exiting the remote shutdown station 10, further ensuring the safe operation of the remote shutdown station system of the nuclear power plant; the operator workstation module 100 is connected to the DCS of the nuclear power plant The monitoring network is used to receive and process the same monitoring information as the main control room when the main control room is unavailable; the monitoring function and monitoring scope of the remote shutdown station system of the nuclear powe...

Embodiment 2

[0044] The present invention also provides a method for remotely shutting down a nuclear power plant, combining the Image 6 ,include:

[0045] Step S1, setting up a remote shutdown station 10 on the unconventional inspection and evacuation path of the safe factory building; further ensuring the safe operation of the remote shutdown station system of the nuclear power plant;

[0046] Step S2, establishing an operator working module 100 in the remote outage station 10 so that it receives and processes the same monitoring information as the main control room; the monitoring function and monitoring scope of the remote outage station system of the nuclear power plant are enhanced, and the need for monitoring is reduced. Reliance on local operation solves the problem that part of the process system logic must be forced to automatically switch to the remote shutdown station due to limited monitoring means;

[0047] Step S3, switching to the operator working module 100 or the main c...

Abstract

The invention provides a remote shutdown station system and method for a nuclear power plant. The remote shutdown station system comprises a remote shutdown station, an operator workstation module arranged in the remote shutdown station, and a switching unit assembly arranged inside and outside the remote shutdown station; the operator workstation module is used for receiving and processing monitoring information identical to a main control room when the main control room is unavailable; the switching unit assembly is connected with a logic control cabinet and is used for sending a switching instruction according to different states of the nuclear power plant; the logic control cabinet is in communication connection with the main control room and the operator workstation module and is usedfor receiving the switching instruction, performing logical processing on the switching instruction, and then switching to the main control room or the operator workstation module to receive and process monitoring information in a distributed control system (DCS) monitoring network of the nuclear power plant. The invention solves the problem that a part of process system logic is forced to be automatic when being switched to a remote shutdown station system due to limited monitoring means, and the monitoring range of the monitoring function is enlarged.

Description

technical field [0001] The technical invention relates to the technical field of nuclear power plant operation, in particular to a nuclear power plant remote shutdown system and method. Background technique [0002] The remote shutdown station is the only backup monitoring and control centralized place when the main control room is unavailable, so it plays a very important role in the operation of nuclear power plants, and plays a key role in maintaining the safety of nuclear power plants and reducing the probability of nuclear accidents. When the main control room of the nuclear power plant is unavailable, there is no remote shutdown station or it is unavailable when it is put into operation, the nuclear power plant will be in an unsupervised and uncontrollable state, and the consequences can be imagined, which will greatly endanger nuclear safety and security. The public environment may cause irreversible social impacts; if the remote shutdown scheme is not sufficient and ...
