Abstract
PURPOSE: To avoid the trip of a generator as much as possible by storing in advance a rectifier fault pattern for excitation of a synchronous generator, comparing it with the pattern, and providing a discriminator for discriminating the fault pattern with the comparison.
CONSTITUTION: The excitation thyristor rectifier of the field 4 of a synchronous generator 3 is connected in parallel in a plurality of number and thus connected with predetermined allowance for rated current. A load run-back controller 37 applies a signal from a field current detector 29 and a signal from a rectifier fault pattern discriminator 30 receiving signal contacts 18a of respective phases to an alarm and run-back instructing unit 31 to conduct load run-back operation. Accordingly, when the rectifier is partially defected, the controller 37 compares the present field current value with the allowable maximum current value of normal rectifier to generate an alarm and to control a turbine 34 with an instruction dispatched thereto. Thus, the trip of the generator can be avoided as much as possible.
