| Abstract |
The start of induction motors in converterbased microgrids poses particular challenges for gridformingconverters due to the limited over-current capabilities.To avoid undesirable over-current operation ofthe converters during start up, suitable current limitationmethods are required to limit both the provided amplitudeand the provided angle of the grid-forming control in anappropriate way. In this paper, a grid-forming controlwith voltage phasor based current limitation is validatedusing power hardware-in-the-loop for the case of inductionmotor start up in an exemplary industrial microgrid.For validation, two different prioritization methods ofamplitude and angle prioritization of the provided voltagephasor are analyzed during current limiting operation atstart up with different torques of the induction motor. |
