Abstract
An electric generator includes a turbine wheel configured to receive process gas and rotate in response to expansion of the process gas flowing into an inlet of the turbine wheel. A rotor is coupled to the turbine wheel and can rotate with the turbine wheel in a stator. The electric generator generates a current upon rotation of the rotor within the stator. A power electronics system is electrically connected to an electrical output of the electric generator and receives alternating current from the electric generator. The electric generator includes a brake resistor assembly having an impedance that matches an impedance of the electric generator. A contactor is electrically connected the electrical output of the electric generator and is configured to connect the electric generator to the brake resistor assembly based on a fault condition.
