核电数字化控制系统与第三方系统接口研究

Research of the communication between the third-party system and digital control system of nuclear power plant

随着数字化控制系统DCS广泛应用于核电厂,核电厂主控室也在向功能更完善、布局更集中的先进主控室过渡,这一技术特点使得主控室操纵员主要依赖操作员站上的显示器和键盘鼠标实现对电厂工艺系统的监控,因此需要将DCS以外的第三方仪控系统与DCS系统进行信息与监控集成。基于此需求,介绍了接口设计的一般原则,具体阐述了福清核电DCS系统与第三方仪控系统接口设计,并以DCS与KRT系统接口为实例,论述了采用I/A平台FDSI模块实现第三方仪控系统接口的具体实施。

As the DCS is widely used in nuclear power plants,the main control room of nuclear power plants is also transitioning to an advanced main control room with better functions and more centralized layout.This technical feature makes the main control room operator mainly rely on the CRT and keyboard and mouse on the operator station to realize the monitoring of the plant process system,so it is necessary to integrate the third-party system with the DCS system for information and monitoring.Based on this requirement,this paper introduces the general principles of interface design,specifies the interface design between DCS system and third-party system of Fuqing Nuclear Power Plant,and discusses the implementation of using FDSI module of I/A platform to realize the interface between third-party system,taking the interface between DCS and KRT system as an example.
