The Design And Implementation Of The Transformation Of Zhangjiakou Thermal Power Plant Unit

The list of signals used in the control and automation system design of Zhangjiakou power plant is based on the electronic table software configuration tool.This tool has the following disadvantages: data maintenance difficulties,manual workload,and the configuration of the signal data list of traceability.Maintenance difficulties are caused by the huge power plant size,the increasingly strict customer needs and different formats of the information caused by the software file.To completely solve these problems,it is needed to develop a new database solution.In this paper,the requirement analysis,function description and high level modeling of database are included.After determining the main stakeholders of the database system.They were involved in an interview with questions about the collection of information about creating a list of signals.The development work is under close cooperation with the Zhangjiakou power plant R & D department,project management and control system suppliers.The theory of database design and requirement management is collected from scientific literature.This theory is used to identify the needs of the early stages of database development and to create a database of conceptual models.The main purpose is to collect requirements information,and create the current existing problems and find solutions to solve the planning database can be implemented.The result shows that the number of signal collection are still distributed in different data base,the existing problems and the reasons that power plant project design and the control system of it at a glance;classified database solutions,basic functions of database modeling,in order to meet the configuration of power device of the signal for the future demand and other information systems connectivity and signal design cycle management.
