Reconstruction and extension method for secondary circuit of transformer substation

Abstract

The invention provides a reconstruction and extension method for a secondary circuit of a transformer substation. The method comprises the following steps: analyzing a transformer substation SCD file to obtain node information of transformer substation IED equipment; defining combination attributes of the transformer substation IED equipment according to the transformer substation IED equipment node information; constructing a visual list of the transformer substation IED equipment according to the node information of the transformer substation IED equipment and the combination attributes of the transformer substation IED equipment; analyzing the transformer substation ICD file to obtain node information of transformer substation ICD equipment; defining the combination attribute of the transformer substation ICD equipment according to the transformer substation ICD equipment node information; constructing a transformer substation ICD equipment model source according to the transformer substation ICD equipment combination attributes; and reconstructing and expanding the secondary circuit of the transformer substation according to the visual list of the IED equipment of the transformer substation and the model source of the ICD equipment of the transformer substation. According to the method, the reorganization and expansion of the secondary circuit of the transformer substation can be realized based on the backtracking analysis of the SCD, and the reorganization and expansion process is visualized, so that the retrotraceability and continuity of the reorganization and expansion work of the secondary circuit of the transformer substation can be improved.

Description

Technical field [0001] The present invention relates to the technical field of intelligent substation, and more particularly to a secondary circuit change of substation. Background technique [0002] Currently, smart substations have entered a comprehensive construction application phase. By the end of 2016, more than 3,000 new smart substations have been built, and the technical system and a series of technical standards of intelligent substation are perfect. Its theoretical research, technology research and development, key equipment development, test system, standard formulation and engineering applications have achieved significant results, significantly improved the safety, controllability, adaptability and interactivity of substations, improve construction efficiency, and promote The transformation of the development mode of the power grid. [0003] In this process, since the intelligent substation is widely used in IEC61850 communication technology, the structure and morph...
