The Application Of Hitachi HIACS5000M System In Thermal Power Plant

Along with the automation in the field of industrial development speed,the distributed control system,referred to as DCS system,has been deeply rooted in the industrial field,is now the mainstream of industrial control system.DCS system is a new type of computer based control system,which is generally called distributed control system in china.Because of the widely used and reliable,quickly occupied the most proportion of domestic control field.Distributed control system is a computer based system,which includes process control level and process monitoring level,and uses communication network to transmit information.Integrated computer technology,graphic phenomenon technology,control technology,information and communication technology and many other technologies,can be monitored and dispersed or centralized monitoring and control system.It has the advantages of convenient management,decentralized control,centralized monitoring,flexible configuration and convenient configuration.Distributed control system of Datang International Zhangjiakou power plant for 8 units to carry out a large-scale transformation,the thermal power plant of 8 units are using the HIACS 5000 M system of Hitachi company,the system is a distributed control system of Hitachi company summary generator decades of system design,production and application experience with control and development the international advanced level.Because the system running time is not long,but there is a big difference in many ways and before use,so it is necessary for the application of Hitachi HIACS5000 M system in thermal power plant to conduct a thorough research.This paper will introduce the system from three aspects: hardware composition,human-computer interaction station and practical application.,which contains three aspects: the composition of HIACS-5000 M system,also has a certain practical value,is a detailed analysis on Hitachi HIACS5000M system.
