Overload protection device for wind farms

摘要

The overvoltage protection device has an inductor formed between a wind energy plant (1) and a network (9) to connect at a connection line (2). A control unit (4) is operated in connection to the overvoltage at the wind energy plant. A limiting device has a transmission line (32) having a power branching module (30) and an impedance module (31) provided with a switch unit.
