核电厂仪控系统，在工程中其控制器执行频率并不完全相同。本文基于RINSIM仿真平台，实现了对Ovation非安仪控系统的仿真，选取了汽机控制系统的设计数据，使用不同的控制模块执行频率在全范围模拟机上进行对比研究，研究结果表明不同的执行频率会大大影响仿真结果，执行频率的选取需严格与核电机组一致。
The control frequency that the controller takes is not exactly the same in nuclear power plant control system. This paper finishes the simulation of non-safety DCS based on RINSIM platform and fingers out that the different control frequency influences the simulation effect, then chooses the turbine control system design reference and uses the different control module control frequency to research the calculation effect. The result proved that the different control frequency can highly influence the simulation results, and the control frequency should be consistent with the nuclear power plant control system.
