METHOD FOR OPERATING AN ELECTRICAL CONVERTER, CONTROL UNIT, AND CONVERTER ARRANGEMENT

A method for operating an electrical converter (22) is provided. The electrical converter (22) electrically couples a generator to a grid (28). The method comprises: receiving an input vector (v, i) being representative of a power parameter of the electrical converter (22); determining an internal voltage reference value (Vref) and an angle (ϕ) referring to a frame angle of the electrical converter (22) depending on an original current reference vector ( idqref,orig) and on the received input vector (v, i); and determining a control signal (CS) for the electrical converter (22) depending on the internal voltage reference value (Vref), the angle (ϕ), and the original current reference vector ( idqref,orig).
