现场总线控制系统(FCS)作为一种数据传输和控制方式,在现代过程控制中扮演着重要的角色。但由于受其类型繁多和电厂控制系统传统结构的影响,目前在火电厂控制系统中的应用刚刚处于起步阶段。火电厂采用FCS与传统的DCS相比,具有彻底的分散性、更好的开放性、良好的互操作性和低成本等优点,明显提高电厂控制系统的自动化水平。 Fieldbus Control System (FCS) plays an important role in modern process control as a data transfer and control method. However, due to its variety and the traditional structure of power plant control system, the application in the control system of thermal power plant is just in its infancy. Compared with the traditional DCS, the FCS used in thermal power plants has the advantages of complete dispersion, better openness, good interoperability and low cost, and obviously improves the automation level of the power plant control system.
