国产Profibus现场总线控制系统在火电厂的全面应用

摘要

自主研发的国产Profibus现场总线控制系统——FCS165在华能陕西秦岭发电有限公司(华能秦岭电厂)600 MW超临界燃煤机组主控及全厂辅控系统中已成功投运.介绍该电厂主机和辅助车间控制系统现场总线技术应用范围,以及现场总线设备信息的开发和应用情况(包括主站状态信息、Profibus-PA设备信息、Profibus-DP设备信息等).FCS165系统不仅运行可靠,能满足机组安全、经济运行的要求,而且利用Profibus现场总线的设备诊断信息及状态信息,实现了现场设备远程诊断和管理功能.%The independently-developed Profibus control system-FCS165 system successfully comes into service in the primary and auxiliary control systems of Huaneng Qinling Thermal Power Plant equipped with 600-MW supercritical units. The applicable range of this fieldbus technology in the primary and auxiliary control systems, and the development and application of the fieldbus device information (including the master state information, Profibus-PA equipment information, Profibus-DP equipment information) are introduced. The FCS165 system runs reliably, which not only meets the safe and economic requirements for the units, but also realizes remote diagnosis and management for field equipment with the diagnosis information and the state information from the Profibus.
