Abstract
The rising proportion of nonlinear electrical consumers causes the harmonic load of electrical distribution systems to increase. Depending on the acting grid impedance this leads to either complied permissible limit values of harmonic load or a danger to safe grid operation. Exemplary Hamburg’s sewage treatment plant is chosen to record harmonic load by means of a developed measurement concept during regular energy supply by the distribution system operator. The acquired measurement data are integrated into a simulation model to infer the harmonic load when operated in island mode, where grid impedance is greater as if connected to public grid. A measure to comply with the limit values is presented and demonstrates the effectiveness of passive filters.
