Modellierung und Berechnung der mutuellen niederfrequenten induktiven Kopplung

The determination of inductive influences, as well as the development of measures to reduce these inductive coupling effects, needs approaches and models to calculate inductive interference phenomena under realistic conditions. Due to the increased grid expansion and the resulting growing number of in close vicinity parallel routed power lines in so-called energy corridors, higher electrical transport loads and short-circuit power as well as more complex transmission systems, the classical influence calculation methods are no longer sufficient to achieve satisfactory solutions.

This article deals with the modelling and calculation of the low frequent mutual inductive interference. A new approach is developed to determine the mutual inductive interference under realistic conditions. Using this approach in addition to determining the inductive interference effects the opportunity to determine unbalance currents and ohmic disturbances with the help of a complete inductively coupled model is given.
