核电厂数字化控制棒控制系统设计技术研究

Study on the Design of a Digital Rod Control System for Nuclear Power Plant

介绍了核电厂控制棒控制(简称棒控)系统的主要功能以及三代非能动核电厂棒控系统的设计要点。在国内现有棒控系统设计的基础上,针对数字化棒控系统设计中存在的难点,提出了基于DCS以及FPGA+DSP控制器的数字化棒控系统设计理念,并详细分析和研究了棒控系统逻辑柜和电源柜两大功能设备的数字化设计方案,总结了该数字化棒控系统方案的优点。

An introduction is presented to the main functions of the rod control system in a nuclear power plant and corresponding design points for the third generation passive nuclear power plant.In view of the difficulties existing in the design of current domestic rod control systems,a design concept was proposed for the digital rod control system based on DCS and FPGA+DSP controllers,with focus on the analysis and research of the two major functional devices:logic cabinet and power cabinet.The advantages of the design scheme for the digital rod control system were finally summarized.
