摘要: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。

Abstract: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.
Key words :DCS;third-party system;network communication;hardwired connection

0 引言

目前核电厂一般采用全范围数字化控制系统(Digital Control System,DCS)系统[1],从系统结构上分为一层(自动控制和保护层)和二层(电厂操作和管理信息层)[2]。一层划分为安全级的保护和监视系统、非安全级控制和监视系统,安全级系统主要完成紧急停堆、专设安全设施及支持系统驱动、事故后监视和处理等安全级功能,非安全级系统主要完成在正常工况下电厂运行监控等非安全级功能;二层亦称电厂计算机信息和控制系统,主要承担电厂数字化操作任务,电厂计算机信息和控制系统通过电厂机组网络获得电厂的输入数据并进行处理,然后把处理结果送到显示装置,为电厂运行人员提供电厂状态的信息及操作指导,同时接受操纵员的命令,把命令传递到一层,实现对电厂的操作。
