Research and Development of Grid Model Online in E Imported to DIgSILENT

To integrate DIgSILENT/PowerFactory into the core computing tool of the high-level application platform for dispatching operation and planning analysis, this paper studies the automation technology of importing online grid models to DIgSILENT and exporting calculation results to DIgSILENT. Based on IEEE9 node, it studies the data content and format of grid device models, topology models and graph models in DGS interface file. A test is conducted to verify the feasibility of using DGS interface to import the entire grid models. Then it compares and analyses the online grid models in E text and the grid models in DGS interface file, studies an approach to the automatic generation of grid graphic data in DGS format based on topology data, and designs a process of converting online grid models in E text into grid models in DGS interface file. At last, this paper develops a software and tests its function. It also analyses and summaries the debugging experience of setting the node type in flow calculation. The content and achievement of this paper will play a guiding role in promoting the application of DIgSILENT for online operation analysis and offline rapid prototyping.
