The Research And Realization Of Electrical Power System Visualization Based On CIM

The electric power dispatch is the key department of electric power system operation.With the advancement of electric power enterprise informationization, many integrated and distributed visual applied-systems and software have been established in electric power dispatch. They not only increase the efficiency of electric power system operation, but also bring some problems. Because these systems were developed during different periods, the data style and interface between them may conflict. The amity of the interface in the software of electric power dispatch also requires the visualization of power grid. The 57th technology committee of the International Electrotechnical Commission (IEC) put forward the sequence of IEC61970 standard for the data and information exchange in the visual software of power grid dispatch, and it also clearly put forward a standard of Common Information Model (CIM) for the interchange of electric power grid model information. There is not mature international standard now for the graphics interchange format in power system and IEC61970 suggests using the standard of Scalable Vector Graphics (SVG).Hence, how to be familiar with the standard of SVG and how to use the CIM/SVG standard in the interchange for electric power dispatch visualization software based on the analysis and familiarity for the IEC61970CIM standard of electric power grid model have come to be a popular topic. The main tasks of this paper are described as follows: Establish the 7 Layer Tree Structure to reflect the CIM model and accomplish the CIM/XML data file parsing job.Tell the application of SVG in the visualization research of electric power system. After that, based on the characteristic of SVG, this paper tells the electric power system info visualization schema using SVG.Investigate the interoperable function of the graphics element description by SVG. By using the CIM/XML file of a provincial electric power grid, establish a transforming model from electric power system CIM/XML file based on CIM to the graphics of SVG format. Design and realize the auto-transforming software platform from typical CIM model CIM/XML file to SVG file.For a substation, this paper analysizes the three types of topological connection between equipments and establishs the graphic data structure. After that, the paper puts forward the automatic layouting algorithm and then realizes the automatic graphic generating by Java coding.
