超临界火电机组在线性能监测系统研究

摘要

An online unit performance monitoring system based on embedded control system was proposed and the real-time monitoring of power-plant unit has been realized. The device of unit online performance monitoring system based on 51 MCU system was studied and its hardware architecture was designed. The communication platform was built between DCS system and the unit online performance monitoring system,and the calculation software module of unit's thermal economy was compiled for the unit online performance monitoring system. In a laboratory DCS simulation environment of a supercritical unit,the operation results shows that the unit online performance monitoring system able to meet the computing needs of power-plant production site in the paper.%该文提出一种基于嵌入式系统的机组在线性能监测系统,实现了火电机组的在线性能监测.研究并设计了基于51单片机系统的机组在线性能监测装置的硬件体系结构,搭建了DCS系统与机组在线性能监测系统的通讯平台,并为机组在线性能监测系统编制了机组热经济性计算软件模块.在某超临界机组实验室DCS仿真环境下的运行结果表明,该机组在线性能监测系统能够满足电厂生产现场的在线性能计算需要.
