HVDC Systems Studies with Power-Hardware-inthe-Loop Experiments

​RT Spotlight Zurich - Topic of the presentation is the validation of HVDC systems studies with Power-Hardware-in-the-Loop (PHIL) experiments. After a short introduction to this field of research -- depicting real-time simulation as the centre spot --, a workflow of designing a PHIL setup with the institute’s available equipment will be presented through an example study case, especially regarding scaling and interfacing methods. Then, the steps necessary to enhance the PHIL setup for validation of studies on meshed grids will be depicted, namely the design of Modular Multilevel Converters (MMC) for scaled PHIL experiments.
