Nuclear power station simulation instrument control system DCS transformation closed-loop verification system and method

Abstract

The invention relates to a nuclear power station simulation instrument control system DCS transformation closed-loop verification system and method. The system comprises a simulation server, an operation display terminal and a virtual DCS server which are connected through network communication. The operation display terminal receives the initial condition and verification operation information inputted by the user and transmits the initial condition and verification operation information to the simulation server and displays the simulation result of the simulation server and the DCS verification simulation result of the virtual DCS server. The simulation server simulates the nuclear power station system equipment state and physical parameters according to the initial condition and based on the full scope simulator process system simulation model and outputs the simulation data. The virtual DCS server receives and processes the simulation data and then returns a DCS operation instruction to the simulation server and outputs the DCS simulation result to the operation display terminal to be displayed. Nuclear power station simulation instrument control system DCS transformation closed-loop test verification can be realized so that the major potential problems of digital transformation can be discovered in advance, controllable upgrade implementation risk and controllable construction period can be realized and the requirements of safe and stable operation of the unit can be met.

Description

technical field [0001] The invention relates to the technical field of nuclear power, and more specifically relates to a closed-loop verification system and method for DCS transformation of a nuclear power plant analog instrument control system. Background technique [0002] At present, digital instrumentation and control technology is becoming more and more mature, but the analog instrumentation and control system equipment of some nuclear power units in service is aging, spare parts are out of production, the failure rate is increasing, and the safety and economy are significantly reduced. Therefore, it is very necessary to upgrade the digital instrument and control system of this kind of nuclear power unit. Compared with newly built digital nuclear power units, the step-by-step DCS upgrade needs to consider the risk of equipment interface with other systems of the unit and the risk of construction period, and there is no corresponding quality risk of comprehensive cold an...
