Research on the Visualization Technology of the Secondary Circuit of Intelligent Substation Based on CIM/G

With the wide application of IEC 61850, the actual electrical connection of the cable in the intelligent substation has been replaced by the other media such as the optical fiber, which directly causes the invisibility of the secondary circuit and brings inconvenience to the operation and maintenance. To solve these problems, the visualization technology of the secondary circuit of intelligent substation based on CIM/G is proposed in this paper. The automatic parsing technology of the secondary circuit connection relationship in the SCD file is introduced, together with the automatic generation technology of the visual interface. The visualization technology adopted here not only realizes the static layout of the physical circuit and the logic circuit in the monitoring interface, but also achieves the dynamic refresh of the graphical objects which reflects the real-time status of the circuit. Finally, the effectiveness of the proposed methods is successfully demonstrated by the practical application, and the comprehensive performance of this automatic visualization technology is evaluated to be superior to the traditional manual mode.
