Design and Development of SCD File Management and Control System for Serving Substation Reconstruction and Expansion Projects

In the design, equipment debugging, project management and acceptance of the smart substation reconstruction and expansion project, the substation configuration description (SCD) file needs to be revised repeatedly. The traditional manual modification method can easily lead to the incorrect modification of the parameter configuration of the equipment that has been put into operation, which affects the safe and stable operation of the secondary equipment. Therefore, the SCD file management and control system is designed and developed to better meet the needs of the reconstruction and expansion projects. Therefore, this paper designs and develops SCD file control system to better meet the needs of reconstruction and expansion project. The system adopts SCD file decoupling and automatic reconstruction technology based on related equipment to ensure the independence of each model clipping file and effectively reduce the influence range of SCD file changes. Through the permission management, the concurrent modification of model files is realized, which greatly improves the efficiency of project construction. Through visualization technology, the changes of SCD files in the construction process can be displayed intuitively. Through the document automatic verification, reduce the workload of designers. The pilot project shows that the system can meet the demand of model file control in each link and stage of reconstruction and expansion project, and help to improve the quality of project construction.
