About us


On the 12th February, the workshop "Safe power generation and distribution in a dynamic environment" took place in our house. In this context, own experiences, possible solutions and the theory behind asynchronuous machines, soft starters and frequency converters were discussed. Why a variety of challanges are connected with the transition from grid-parallel to stand-alone grid operation was not only theoretically and simulatively possible, but also practically tested and recorded in the test field on a small island grid model. We thank all participants for the numerous contributions and the positive feedback on our joint workshop.
