Abstract
The invention relates to a method for inputting power into a multiphase alternating current grid by means of a transformer () which is electrically interconnected between the alternating current grid and a number of input phases (, (p) corresponding to the number of grid phases (O) of the grid, wherein at least one voltage characteristic (Ueffl, Uef˜, Ueff) of one of the grid phases (O) is determined, and an input of reactive currents occurs as a function of a previously determined deviation (AU, AU, AU) of the voltage characteristic (Ueffl, Ueff, Ueff) of the at least one grid phase (O) relative to a corresponding target voltage characteristic (Usoll). It is provided that the deviation of each one of the voltage characteristics (Ueffl, Ueff, Ueff) is determined, and the input of the reactive currents in case of deviations that are asymmetrical with respect to the symmetry of the target voltage characteristics is an asymmetrical input of the reactive current with respect to the respective input at the input phases (, (, (). The invention further relates to a corresponding system () for inputting power into a multiphase alternating current grid.
