摘　　要：提出了基于OPC通信技术的后台复杂控制算法应用程序的集散控制系统(DCS)构架。利用组态软件,设计了针对火电厂主蒸汽温度的DCS监控界面。采用组态软件ForceControlR自带的PCAuto.OPCServer作为OPC服务器,利用Simulink工具箱搭建系统现场的仿真框图,并采用工具箱自带的OPC接口与组态软件OPC服务器建立一个连接。同时利用MATLAB编写与OPC服务器建立另一个连接的后台控制算法应用程序,并将该程序编译成可执行文件以供组态软件随时调用。通过对该系统的仿真实验表明,该系统运行稳定、可靠。An architecture of DCS（Distributed Control System） is proposed,which has the algorithm application based on OPC（Object linking and embedding for Process Control） communication technology for the complex background control. The configuration software ForceControl is used to design the front interface of DCS monitoring system for main-steam temperature of thermal power plant and its PCAuto.OPCServer is used as the OPC server. The Simulink toolbox is used to build the block diagram for site system simulation and its OPC interface is used to communicate with the OPC server. The interface between the back control algorithm application and OPC server is programmed with MATLAB,which is compiled as an executable file for the convenient call by the configuration software at any time. Simulation and experiment prove that the proposed system is stable and reliable.
