FLEXIBLE REACTIVE POWER COMPENSATION

An arrangement for reactive power compensation at an electric energy transmission line includes at least one first reactive power compensation device including a first type of power electronic switches, at least one second reactive power compensation device including a second type of power electronic switches and a transformer having a first secondary coil connected to the first device, a second secondary coil connected to the second device and a primary coil connectable to the electric energy transmission line. The primary coil has more windings than any of the first and second secondary coils.
