Research On Substation Equipment Operation Simulation Training System Based On New Web Technology

In order to make students intuitively feel the process of switching operation to facilitate them deep understanding and mastery of the principles and norms of switching operation, so as soon as possible into their future work roles, as much as possible to avoid misoperation, the training opportunity to prevent misoperation for students becomes very real and important. Therefore, design and develop a set of substation equipment operation simulation training system based on Web new technology, advanced in idea and technology, has practical significance.On the basis of the analysis and research in the advantage and disadvantage of multiple software architecture, design a novel substation equipment operation training system structure based on SOA, divided into the presentation layer, Web services layer, business logic layer and data access layer. First, in the understanding of the advantages and disadvantages of multiple software development tools, Microsoft’s.NET development platform is selected as the system development tool. Secondly, in the.NET development platform, Windows Forms power flow calculation application based on the method of PQ decomposition is achieved, providing support for the power flow display; according to the idea of "Five anti-logic", switching operation business logic has been realized; design and define the attributes and elements of breaker, disconnector, transformer, bus and other electrical equipment data table, as well as the relationship between the tables, and make the use of ADO.NET to achieve effective access to the database. Then, make use of Silverlight technology to design and develop the system login interface, switching operation interface and power flow display interface, and realize the interface between the jumps, and improve the background C#program to the interface; the method of developing services and managed way to Web services are studied, and many fine-grained services such as the bus switching operation are encapsulated by WCF technology. Finally, the system service has been deployed into IIS (Internet Information Server), and achieves the Smart Client on the domain and cross-domain call for Web service.The system realizes the switching operation simulation training function based on the physical process of the actual substation and logic relation. The system, user-friendly and simple operation, has achieved design purpose for the principle show.
