成果简介	NOVELTY - The system has first automatic excitation regulator (1) connected to a thyristor converter (5) through first control unit (9). Second excitation control channel consists of second automatic excitation regulator (2) connected to IGBT transistor (6) through second control unit (3). First and second automatic excitation regulators are synchronized for alternate activation of excitation channels by transmitting a current of setting value to corresponding first and second control units. The first control unit regulates value of current at output of the thyristor converter by changing duty cycle of pulse-width modulation transmitted to the converter. The second control unit regulates current value at output of the IGBT transistor by changing duty cycle of pulse-width modulation transmitted to the transistor. The outputs of the converter and the transistor are combined into one conductor with possibility of connecting to excitation winding (8) of exciter of brushless synchronous generator. USE - Two-channel excitation control system for brushless synchronous generator. ADVANTAGE - The reliability and speed of operation of the excitation control system are increased. DESCRIPTION OF DRAWING(S) - The drawing shows the block diagram of the two-channel excitation control system for brushless synchronous generator. 1First automatic excitation regulator 2Second automatic excitation regulator 3Second control unit 5Thyristor converter 6IGBT transistor 8Excitation winding 9First control unit
