A pump valve simulation device and a phase sequence detection and relay cabinet of the semi-physical simulation system are connected with a signal input cabinet. The signal input cabinet, a signal output cabinet and a test control console perform Ethernet communication through a network switch. The method for debugging the nuclear power unit control system by the adoption of the semi-physical simulation system includes the steps that the semi-physical simulation system is connected with the nuclear power unit control system to form a loop; a simulation computer of the semi-physical simulation system is simulated into a nuclear power unit, and a signal source of the nuclear power unit control system is tested; according to user requirements, the operation function of the nuclear power unit control system is tested. The closed-loop debugging method is utilized for debugging the logic control function and progress control function of the nuclear power unit control system.

Description

technical field [0001] The invention relates to the field of nuclear power devices, in particular to a semi-physical simulation system and method for debugging a control system of a nuclear power device. Background technique [0002] Nuclear power plant is a device that replaces ordinary fuel with nuclear fuel and uses the fission reaction of nuclear reactor core fuel to generate heat energy and convert it into power. The nuclear fuel produces fission reaction in the reactor of the nuclear power plant, releasing huge energy, which is absorbed by the continuously circulating cooling water, which in turn transfers heat to the water in the second circuit through the steam generator, turning it into steam and then to work in the steam turbine. see figure 1 As shown, the nuclear power plant control system includes a console 8 , a controller 9 , actuators (such as pumps, valves, etc.) and a signal acquisition device 7 . The working principle of the nuclear power plant control s...

Problems solved by technology

This open-loop debugging method can only check the control ability of each controller to the actuator one by one, and cannot verify the execution ability of the actuator at the same time, that is, it is impossible to debug the logic control function and process control function of the control system of the nuclear power plant: logic control function It refers to the ability of the controller to control the start and stop of the actuator; the process control function refers to the ability of the controller to control the performance of the actuator, specifically refers to the controller's adjustment of the valve opening, pump speed and other signals
