Simulation platform for rod control system of nuclear power station

Abstract

The invention discloses a simulation platform for a rod control system of a pressurized water reactor nuclear power station. The simulation platform comprises a simulation and data acquisition cabinet, wherein the simulation and data acquisition cabinet comprises a simulation unit and a data acquisition unit, and the simulation unit outputs a simulation signal; the data acquisition unit acquires a process signal; a manual control console simulates a master control room and outputs a control signal; a logic cabinet produces a rod position movement command; a power cabinet comprises a circulatory monitoring logic unit and a silicon controlled rectifier circuit, and the circulatory monitoring logic unit controls the silicon controlled rectifier circuit to output a coil running signal; a load simulation cabinet simulates lifting and thrusting actions of a control rod according to the coil running signal; and a distribution box is used for power distribution of all the other cabinets. As the simulation platform for the rod control system of the nuclear power station comprises all typical equipment of the rod control system, on-site equipment failure analysis and maintenance of the rod control system, functional verification and burning of key equipment, and technical training and software and hardware operation training of on-site maintenance personnel of the rod control system are realized.

Description

technical field [0001] The invention relates to the field of rod control systems in nuclear power plants, in particular to a simulation platform for rod control systems in nuclear power plants. Background technique [0002] Control rod control system (referred to as rod control system) is one of the main reactor control systems. Its main function is: according to the change of grid load, the system correspondingly raises or inserts control rods to adjust the reactivity of the reactor core, thereby controlling the core temperature and Nuclear power, enabling reactor control in G-mode. When the reactor is in an unstable operating condition, the control rod control system can also bring the reactor from zero power to full power during the reactor start-up phase and perform shutdown during the normal shutdown phase or emergency shutdown in case of an accident to protect the reactor. Ensure core safety. The rod control system mainly includes three parts, which are rod control l...

Problems solved by technology

This maintenance method has three disadvantages: 1) The spare parts are put into use without functional verification, which brings certain risks to the running unit; 2) Since there is no verification means, the replaced spare parts cannot be diagnosed and repaired independently; 3) Due to the production stoppage of the manufacturer or the long maintenance cycle, the number of on-site spare parts cards is gradually decreasing, and the pressure on the supply of on-site spare parts is increasing day by day, and the maintenance cost of the board parts is also inflated due to monopoly.
