Research On Cooperative Modeling Scheme Between Substation And Dispatch Center Based On Integrated Model Data And Graphics

In the power systems, substations model follows IEC61850 standard, while control center model follow IEC61970 standard. The differences between the two standards, resulting in not only a heavy workload modeling in dispatch center, but also poor real-time and high error rate maintenance, which is unable to meet the needs of a variety of distributed applications of the smart grid.In order to enhance maintainability of substation model, this thesis presents a new whole-information model of the substation and control center, and based on this information model this thesis also presents a chart-module integration collaborative modeling scheme. The new model contains the information of SCL model and the CIM model, so that the SCD file and CIM/E files can be generated through information extraction and formatting changes. To achieve chart-module integration of substation configuration vectors, the grapics files and the model information should be combined. In order to verify the feasibility of the whole information model and chart-module integration collaborative modeling scheme, the software has been developed based on Qt. The implementation of software function has given a good verification of the modeling scheme.
