Research on Application of Software Engineering Science to Control Configuration of Parameter Entry Typed DCS

As the distributed control system(DCS)of power station is getting increasingly large and complicated,the basic content of DCS configuration in power station is analyzed,and it is suggested that the configuration of parameter entry typed DCS be realized under the guidance of software engineering science.Combined with the engineering application examples of 465 t/h circulating fluidized bed cogeneration units,the task,role and implementation method of such steps as demand analysis,systematic analysis and design,coding,testing and maintenance during configuration are expounded.Practical application results show that the development mode can improve work efficiency and realize the multiplexing of configuration document to the greatest extent;the software design document is complete and convenient for extending function and maintaining software.
