摘要

The invention relates to a method for feeding electrical current into an electrical, three-phase power supply system having a first phase, a second phase and a third phase with a first voltage, a second voltage and a third voltage at a power supply system frequency, comprising the steps of: measuring the first, second and third voltages, transforming the first, second and third voltages into a positive phase-sequence voltage system and a negative phase-sequence voltage system according to the method of symmetrical components, calculating a first desired current, a second desired current and a third desired current for feeding into the first, second and third phases of the power supply system, wherein the first, second and third desired currents are calculated on the basis of at least one value of the positive phase-sequence voltage system and/or the negative phase-sequence voltage system.
