Research on agile generation method of electromagnetic transient simulation model based on multiple information sources

Abstract Based on electromechanical transient simulation data, an electromagnetic transient simulation model can be quickly generated through a computer program. However, electromechanical transient data are not sufficient to describe completely the corresponding electromagnetic transient simulation model. In view of this, the paper proposes an electromagnetic transient simulation model generation method that integrates multiple information sources. First, the data characteristics of electromechanical transient simulation software PSD-BPA and electromagnetic transient simulation software PSCAD/EMTDC are introduced. Then, considering the difference between electromechanical transient and electromagnetic transient model data, a method to quickly generate PSCAD/EMTDC simulation data is established. This method is based on the electromechanical transient simulation data, and takes into account those information which is not available in the electromechanical transient data but needed in the electromagnetic transient in the conversion process, so that the converted model is more detailed and accurate. Finally, this method is used to model and analyse an actual fault. The simulation results show that the method proposed in the paper is effective and credible.
