REDUNDANT ELECTRICAL BRAKE AND PROTECTION SYSTEM FOR ELECTRIC GENERATORS

摘要

An apparatus for electric braking and system protection for an electric generator (101) includes a dynamic brake (210) and a crowbar circuit (220) designed for cooperation with power converters to dump power upon command. The dynamic brake (210) includes at least one resistor and the crowbar circuit (220) includes another at least one resistor for dissipating power from the electric generator (101). Methods for use of the electric braking and system protection calls for shunting the power to at least one of the dynamic brake (210), the crowbar circuit (220) and the generator (101) side power converter.
