Development Of Collaborative Modeling System For Thermal Power Station Simulator Based On Object-oriented Technology

Under the rapid development of computer control of the thermal power plant,the simulation model becomes more complicated.At the same time,the number of model is very large.Collaborative modeling system development of thermal power station simulator based on object-oriented technology,with the characteristic of collaborative,can decrease the workload of the modeling engineer effectively.UML,object-oriented language in the software development process,highlights its importance gradually,and creating favorable conditions for the developmen of platform of model support system.The design ideas of the system can be more clear.What's more,a lot of time can be saved in the development and analysis of the software.UML is an kind of object-oriented analysis and design.System can be analysised by the static structure and dynamic behavior with modeling.Any type of system can be described based on the object-oriented method.Then the application domain of UML can be broaden.Based on comparing with traditional development mode and object-oriented development,the system can be described by UML with demand confirmation,analysis,modeling and the whole process from design to implementation.UML as a general standard modeling platform,in the phase of requirements analysis,uses description of cases graph to get the user needs,and uses case modeling to describe the functions of the system.The dynamic model of UML can describe the collaboration between classes,so as to realize the functions of use cases.Models in UML can also be the basis of the test in the phase of testing.From the specification describes to the work of maintenance after the completion of the whole system.The technology of UML has been adopted at different stages of system research.The system can be analysisd by collaboration modeling of power station simulator combining with object-oriented technology.Thus fully verified the feasibility of collaborative modeling system development of thermal power station simulator by UML.This system is a very important part in the construction of simulation system in power station.Based on the demand of model,the big model can be split into pages.And the modeling engineer will make the task allocation,so as to improve the modeling efficiency.Finally,according to the simulation example of power plant,making the demand analysis of collaborative modeling of thermal power station simulator by UML.What's more,the general design and detailed design can be applied.The key technologies are described in detail.The article maks the research explores about collaborative modeling of thermal power station simulator by UML.
