Pressurized water reactor hardware-in-the-loop simulation system based on physical model

Abstract

A pressurized water reactor real-time simulation system is composed of a physical model, dynamic real-time simulation software and other systems. The physical model is the first pressurized water reactor simulation model in China under a proportion of 1:10, which is made of organic transparent material based on the approximate substitution principle, and theoretical guidance is offered to actual operation of a pressurized water reactor by means of research on the simulation model, thus the economic benefit is improved and the development period of novel pressurized water reactor is shortened. Software simulation is achieved using a VC++ / MATLAB hybrid simulation technique, and meanwhile, an excellent interface between the physical model and the simulation software is established to realize dynamic, real-time monitor and control for pressurized water reactor.

Description

1. Technical field [0001] The invention is a patent, which is a simulation system utilizing a combination of a pressurized water reactor physical model and a mathematical model. 2. Background technology [0002] Pressurized water reactors are currently the most widely used nuclear reactors. The existing PWR simulations are mainly divided into the following three categories: one is the three-dimensional simulation model, but the display effect of this simulation model is not intuitive enough to reflect the specific structure of the reactor well; the other is the simplified Simulation of mathematical calculation models based on conditions. This method lacks actual parameter correction and has large errors. Another type is half-physical model and half-software simulation. The physical models of reactors that can be seen now mainly include anatomical models showing the structure of the primary circuit of nuclear power plants. And the static physical model of the whole nuclear p...
