| With the quick development of computer and information technology, the research and application of control system in industry area develops rapidly. Especially, the Distributed Control System which has been defined for the advanced benefit and navar in the industry area, has developed to the brand-new with the more expection for the advanced control and management technology from customer.The Fieldbus Control System is the kind of entire computer, entire digital and more open control system. The digital communication directs the trend and brings out the revolution for the automation. Surely, The Fieldbus Control System represents the direction for the automation technology and application.Due to some politic and economic reasons, the development and application of Field Control System encounters much competition and challenge. Although consulting with each other at certain scope, the entire unified international stand for FCS has not been formed so far long after the warlords among many aspects.Bus-Protocols is the core of the Field Control System. It has been applied in coal-fired power plant successfully and eliminated lots of doubts and suspicions. All these builds up the well public praise for later applictions among the power plant control system market.In the abstract, the Field Control System will bring out the huge benefit for the management and economic for the power industry so far.This thesis mainly elaborates the development of control system in industry area and the advantage of Field Control System. With the more advanced level of digital and control management, the brand-new control system will be illuminated with the actual applications in the coal-fired power plant. This paper is mainly to analysis the features and design of Profibus FCS. With lots of examples and comparations followed with the actual application, we will get a conclusion that Profibus FCS is one advanced technology and will be developed and applied in the expansive area.At present, all the generators above 300MW, whatever coming from oversea or domestic, even 200 MW,100 MW power plants, are furnished DCS control. Some 25, even 12 MW power plants are also been reconstructed to DCS system. So, with the more advantage and wide application scope, the Fieldbus Contorl System which was applied just from late 1990's, surely will be accepted and extended widely by the power station also like DCS system in automation area! And this will also contribute more to the national economic and modernization in future. |
