| Power graphics system is an important part of the power system applications software. The important part about the visualization of power graphics system is the graphical display of the actual power system and the output of a variety of graphical data. On the other hand, after the IEC61850 standard was officially published, more and more transfer substations around the world have put it into application totally and partly. In order to make it truly become the standard on electricity network seamless automation control of the universal communication platform the WG10 working group of IEC TC57 is developing the second edition of IEC61850 standard. The new version will increase the IEC61850-80-1 (map between IEC61850 and IEC60870-5-104/101), IEC61850-90-1 (IEC61850 used to communicate among the transfer substations) and IEC61850-90-2 (IEC61850 used to communicate between control center and transfer substation) and so on. We can foresee that new product will gradually full support IEC61850 standard.This article, which is based on the in-depth study of IEC 61850 standard, discusses the problems of current power graphics display system and tries to apply IEC 61850 configuration file to the graphical topology display system of transfer substation. Firstly, it integrally introduces the frame, composition, function distribution of the power graphical display prototype system, based on the IEC 61850 standard, and the composition relationships of some key technologies. Secondly, the IED modeling methods and characteristics about IEC 61850 are described in detail. At the same time this paper analyses and compares the advantages and disadvantages about the tow ways, one of which is based on relational database and the other one is based on object-oriented database, in modeling of IEC 61850. The specific solutions about IED model access based on object-oriented database are given. And then it give a detailed analysis of IEC 61850 in the SCL language features rules in the combination of SVG graphics technology to conduct a comprehensive analysis of transfer substation configuration files and information matching. And then it designs SVG device graphic based on object-oriented database and presents particular blue print of access about device graphic depot based on db4o database. Subsequently, it gives an in-depth study of the ACSI mapping to MMS of the IEC 61850 and a specific analysis of the file transfer service and some Java-based service solutions. Finally, it proposed the total design plan about the power graphic display system software and gives an analysis about device graphic access, transmission and analysis of the transfer substation configuration file and the topology map displaying process. In the Windows platform, each module programming is completed in Java-based software development environment, and the feasibility of this design is verified through the configuration file of an IEC 61850 transfer substation sample.This article is the study of beneficial effects that may be produced by IEC 61850 configuration file on the future scheduling application. Electrical substation connection diagram, generated by that IEC 61850 configuration file in combination with SVG technology, has some value about the transfer substation construction which is based on IEC 61850 and has entered the engineering phase. In addition, this issue also has some significance prospective study about future application of IEC 61850 standard to the electric power SCADA. |
