Design of an Adjustable Inductor for a Power Grid Fault Simulator

Abstract:
The interaction of many converter-based systems within the power grid already severely affects the supply quality in the network today. The development of a laboratory inspection and test system using "hardware-in-the-loop" (HIL) methods for simulation and investigation makes it possible to investigate potential problems in advance. For the realization of such a simulator a controllable inductance is necessary to simulate faults in the power line of end-user households. The feasibility of such a component is investigated, designed and tested.
