Abstract :
The two 18.75 MVA generators for the Texas Experimental Tokamak (TEXT) upgrade will require coordinated protection and excitation systems. The protection system for each generator will consist of protective relays, a vibration monitor, a temperature monitor, a high-speed breaker, and a braking resistor assembly. For the field excitations, a DC chopper circuit will be added to the original rotating exciter to improve excitation and de-excitation response time. The authors describe the protection and excitation systems and their interdependence in detail
