摘要： A generating unit, GU, with an asynchronous generator with a direct connecting branch to a power grid; a measuring device for determining the profiles of a GU grid voltage and an GU grid current at the power grid; and power electronics connected in parallel with the asynchronous generator and the power grid. The power electronics including an inverter with an inverter output for direct connection to the generator power grid branch; an intermediate circuit energy storage device; and a control unit. Based on the grid current measured and the grid voltage measured, the control unit can determine a phase shift angle and the value of the grid current and, based on this, actuate the inverter such that the value and phase shift angle of the output current of the power electronics assume values that, together with the current of the asynchronous generator, result in a target phase shift angle.
