ENERGY STORAGE ARRANGEMENT AND ALTERNATING LOAD CONSUMER

摘要

The invention relates to an energy storage arrangement (8) for an electric load (4) which exchanges electrical power with an energy supply network (2), comprising two connections in the form of a load (4) to the parallel circuit and for the energy supply network (2), a converter (10) which is switched between the connections (6a, b), is voltage-impressed and contains an energy store (12). The energy store (12) is designed to store an energy amount (E1 + E2 + E3) which exceeds that necessary for the regular operation of the converter (10) by a multiple. An arc furnace which is fed as a load (4) from an energy supply network (2) contains the energy storage arrangement (8).
