FIELD: power industry.
SUBSTANCE: wind power plant contains a rotor with blades, an electric generator connected to the rotor, and a power electronics unit containing a varistor unit and designed to convert the input voltage with input frequency into an output voltage with output frequency. Varistor unit comprises a varistor disk with voltage-dependent resistance and a metal disc, contacting varistor disk, intended for cooling the varistor disk.
EFFECT: increasing the reliability of device by preventing voltage peaks on generator when the load is relieved.
