Expansion of RELAP5 Control and Protection Simulation Functions with Simulinl
-
摘要: RELAP5程序本身具有模拟核电站控制与保护系统的功能,但是,由于该程序采用文本输入方式进行建模,编写复杂,可读性不强,不适合于对大型复杂控制系统进行仿真。而Simulink程序采用图形化建模方式,能够高效、便捷地对核电厂复杂控制与保护系统进行建模。因此,本文将RELAP5程序与Simulink耦合,并利用Simulink扩展RELAP5的控制与保护系统的模拟功能。为了验证两程序耦合方法的准确性,将用Simulink实现的控制与保护系统的仿真结果,与已通过验证的RELAP5实现的具有相同功能的控制与保护系统的仿真结果进行对比,结果表明二者符合较好。

Abstract: The RELAP5 itself is with the abilities to simulate nuclear power plants （NPP） control and protection systems. However, its simulation modeling are text-based, which is complicated and lacks of readability, and above all it is not suitable to model large complicated NPP control and protection systems. Simulink, which uses diagram-based modeling, however, is capable of modeling large complicated systems with high efficiency and convenience. This paper has coupled RELAP5 with Simulink, and also expanded the control and protection functions of RELAP5 with Simulink. To verify the coupling method, this paper has also compared the simulation results of the same NPP control and protection systems simulated by Simulink and RELAP5, respectively, and the comparison result has illustrated a good match between the two. -
