核电站控制保护及辅助系统仿真方法研究

Research on the Simulation Method of Control and Protection System in Nuclear Power Station

分析了大亚湾核电站控制保护及辅助系统仿真模型,采用面向对象编程方法以自编软件形式对大亚湾核电站模型进行模拟,并在开发过程中采用UML统一建模语言进行分析设计,实现了对该大亚湾核电站控制与保护系统的动态仿真。瞬态工况测试结果显示该仿真能较好地模拟反应堆一、二回路的控制与保护功能。本仿真程序具有通用、便携以及廉价等优点。

Simulating of control, protection and auxiliary system in nuclear power plant （NPP） is necessary for improving precision of the NPP simulation. This paper analyzes the models of those systems in DAYABAY NPP. Based on the DAYABAY NPP model, we realize the simulation code through object-oriented programming concepts. The results of transient test events show that the simulation successfully fulfills control and protection function of primary and secondary loop in NPP. The code is more general, portable and low-cost.
