A configuration for stabilizing an AC voltage grid has a rotating phase-shifter that is configured to exchange reactive power with the AC voltage grid. The configuration is distinguished by a converter which has a grid side for connection to the AC voltage grid and a machine side for connection to the phase-shifter. A method is furthermore taught for stabilizing the AC voltage grid by way of the configuration.

In order to create a full variable shunt reactor having two magnetically controllable high-voltage throttles which is compact and at the same time can also provide capacitive reactive power, auxiliary windings are used which are inductively coupled to the high-voltage throttles. The auxiliary windings are connected to at least one capacitively acting component.

A system for stabilizing an alternating voltage grid has an inverter, which can be connected to the alternating voltage grid, and is configured to exchange reactive power with the alternating voltage grid. The system further has an inductor arrangement with variable inductor coils, which can be connected to the alternating voltage grid, and a control device, which is configured to control a reactive power in the alternating voltage grid by use of the inverter and by use of the inductor arrangement.
