On the portability of EMT models in different power system simulation software tools

Abstract

This paper presents the investigation carried out on the portability and compatibility of a model in different simulation software. The offer of simulation software for power system simulation is wide, with each program having its own modelling interface and its own methods of model development. The lack of a widespread standard for portability between applications implies that the same organisation needs to carry out studies on different applications, requiring the development of a model of the same element or system for each application. This study presents an example of the integration of an inverter model in DigSilent, PSCAD and Simulink by means of the Multilink tool. Throughout the article, the differences found when performing the integration and the same simulation scenario in these three simulation tools are listed. It concludes with a comparison of the results obtained from an electromagnetic transients (EMT) simulation in the three simulation software. The results show a greater similarity between PSCAD and Simulink, with respect to the results obtained in DigSilent.
