Embodiment Construction

[0020] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0021] Along with the application of DCS (Distributed Control Systems, distributed control system) in various fields, in the present invention also adopts DCS management in the nuclear power plant, the computer-aided isolation system obtains the thread status of DCS equipment and the operator carries out the isolation function reference. The main data of the computer-aided isolation system comes from the field. Each field (DCS and other control systems) is equipped with a complete card (IO module) to collect electrical signals such as instruments and sensors, and send them to the DCS and other contr...

Abstract

The invention is suitable for the technical field of nuclear power stations and provides an isolation method and an isolation system for the nuclear power stations. In the invention, the method comprises the steps of firstly determining nuclear power station equipment needing to be subjected to assisting isolation by means of a distribution control system (DCS), determining an isolation state value according to the corresponding relation between starting-opening values and the isolation state value of the nuclear power station equipment, and then performing isolation or removing the isolation on the nuclear power station equipment according to the isolation state value. By the DCS-based computer assisting isolation method, the man-made factors are reduced, the safety and reliability of the isolation work are improved and the current state of the equipment to be isolated can be displayed in real time.

Description

technical field [0001] The invention belongs to the technical field of nuclear power plants, and in particular relates to a nuclear power plant isolation method and system. Background technique [0002] The computer-aided isolation system is a set of software systems used by nuclear power plant operators to implement safety isolation. It adopts offline management and manages the status of isolation measures through a series of work processes and strict management regulations. The purpose of isolation is to determine a working boundary that can establish and control safe conditions and provide a safe working environment for on-site workers. A complete isolation means: separating the isolated equipment from energy and working fluids through isolation and strict management , prohibit any operations on the boundary equipment by locking and hanging isolation signs. [0003] The characteristics of nuclear power plant equipment operation and the particularity of nuclear fuel power...
