Comprehensive control system for nuclear power plant BOP process and method thereof

Abstract

The invention relates to a comprehensive control system for a nuclear power plant BOP (Balance Of Plant) process and a method thereof, the system comprises a BOP comprehensive control room shared by all subitems of a BOP system, a man-machine interface device is arranged in the BOP comprehensive control room, a control cabinet communicates with the man-machine interface device in the BOP comprehensive control room through an industrial Ethernet, remote I/O (Input/Output) cabinets used for being connected with field equipment are arranged in all sub-items of the BOP system, the remote I/O cabinets are connected with the control cabinet through a bus, and video/image recognition equipment is arranged in all the sub-items. According to the invention, an independent control room of each subitem is cancelled, so that the number of operators can be reduced, signals sent to a main control room of the nuclear power plant can be reduced, the cost of a main DCS (Distributed Control System) can be reduced, and the burden of operators in the main control room can be reduced. In cooperation with the bus and remote I/O technology, the number of cables can be greatly reduced, and the cable laying cost is reduced. In cooperation with a video/image recognition function, inspection personnel can be reduced, and the operation and maintenance cost of the nuclear power plant is reduced.

Description

technical field [0001] The invention belongs to the design technology of nuclear power plants, and in particular relates to a comprehensive control system and method for the BOP process of nuclear power plants. Background technique [0002] BOP (Balance of Plant, power plant supporting facilities) belongs to the supporting facilities of nuclear power plants, which are used to provide support for the operation of nuclear power plants. BOP facilities are arranged in different plants according to their functions, and a single plant is also called a sub-item. The control of each sub-item is independent of each other, and each sub-item independently sets up a control room and a control equipment room, such as figure 1 shown. The control room is scattered in each sub-item, and each sub-item adopts its own independent control system. The important alarm or display signals of each sub-item are sent to the main control room of the whole plant in the form of hard wiring through the...

AI Technical Summary

Problems solved by technology

This control method has the following problems: 1) The control room is scattered, requiring more operators and inspection personnel, and the operating cost is high; 2) The remote monitoring is set inside the sub-item, and there is overlap with the on-site control function. The monitoring function is not fully utilized; 3) The brand and model of the PLC system of each sub-item are not uniform, and the number of spare parts is large, which is not conducive to operation and maintenance; 4) A large number of signals enter the main DCS (Distributed Control System, distributed control system) of the nuclear power plant and the main In the control room, the number of IO points and the number of boards of the DCS are increased, resulting in a large scale of the main DCS of the power plant, while the cost of the main DCS of the nuclear power plant is relatively high, and the communication method for sending DCS signals is hard-wired, the number of cables is large, and the construction cost is high
