Digitized security level control system simulation device of nuclear power plants

Abstract

The invention discloses a digitized security level control system simulation device of nuclear power plants. The digitized security level control system simulation device is connected with a model server through a network and comprises a security level DCS simulation server and n simulation terminals. The security level DCS simulation server is used for simulating the security level DCS part of the digitized security level control system simulation device. The simulation terminals are used for simulating true display and operation, and n is larger than or equal to 1. The security level DCS simulation server comprises a scheduler (1), an MCS execution process unit (3), an SCID execution process unit (4), an application logic unit (6), a display DB unit (7), a memory sharing unit (8) and a data manager (2). The normal running and fault work conditions of multiple on-site DCSs are simulated through one server, configuration files of the actual DCSs can be analyzed, system monitoring is conducted through practical engineer stations, and the a simulated system can approach a true system to the maximum extent.

Description

technical field [0001] The invention relates to a simulation device used for the training of the instrument control system of a nuclear power plant, in particular to a simulation device of a digital safety level control system of a nuclear power plant. Background technique [0002] The simulator is the key equipment on the main path of nuclear power plant engineering construction. It integrates high-tech in many fields such as reactor engineering, thermal power, electrical, instrument control, etc. Analysis and evaluation play an important role. It simulates the physics, technology and control process of the nuclear power plant through the simulation mathematical model, and uses the computer graphical interface as the simulation system of the human-machine interface. , to realize the operation and operation training of the power station system. [0003] At present, the safety-level DCS simulators put into use in the market are all foreign products, mainly from the United S...

AI Technical Summary

Problems solved by technology

With the accelerated development of my country's nuclear power industry, the purchase of nuclear power plant simulator accessories from abroad is expensive. Once a problem occurs, it will be difficult to solve for a long time, which will directly affect the safe operation of the nuclear power plant.

Moreover, the difference between the simulator and the unit and the difficulty of foreign after-sales service affect the normal use of the simulator and the training process of operators
