核电厂反应堆功率调节系统计算机控制研究

Study on Computer Control for Reactor Power Control System of Nuclear Power Plant

建立核电厂反应堆功率控制系统模型,通过SIMULINK工具建模和仿真,对模型的仿真性能和系统的稳定性及合理性进行验证。在此基础上,采用S7-300系列的PLC作为反应堆功率控制现场执行机构平台,并进行系统组态、编程和实验验证,利用计算机对整个过程进行操作、监测和控制。经功率调节实验验证,系统控制响应稳定可靠,为进一步开展核电厂计算机控制技术研究和控制系统设计奠定了技术基础。

Established reactor power control system model of nuclear power plant, then validated the simulating performance of the model and the stability and rationality of the system. By sysem configuration, programming and experimental validating, used the S7-300 PLC as the spot operation flat to control the reactor power and the computer to operating, watching and controlling the whole process. The responses of reactor power control system are stabilized and credible. The result laid the technical foundation for the further study on the NPP computer control technology and the design for control system.
