In recent years, the medium and small project market, domestic system with higher ratio of performance to price and good service gradually the dominant.In order to understand the NT6000 distributed control system ( DCS ) in Chinas thermal process automation application status, and future prospects, I not only to collect the current domestic thermal power plant production process data and NT6000distributed control system control principle, specific still participated in some NT6000DCS project. Through the study of the various hardware circuit and software logic, profound understanding of NT6000distributed control system in thermal power plant generating process of real-time monitoring and control. In view of NT6000 distributed control system ( DCS ) unique control theory and the solution, I have reason to believe that the future in power plants and nuclear power field NT6000 distributed control system ( DCS ) will play a role can not be ignored.
