ABSTRACT:
An apparatus for compensation of commutation dips in the curves representing synchronizing voltages developed by an excitation system of a synchronous machine comprises a thyristor converter and a matching transformer, and includes measuring transformers. Two of the measuring transformers have their primaries coupled to secondaries and primaries of the matching transformer in antiphase relation to each other, while primaries of a third measuring transformer are coupled to the arms of the thyristor converter in antiphase relation to the primaries of the second measuring transformer. The opposite ends of the primaries of each of the measuring transformers are joined together to constitute common points. The secondaries of the measuring transformers are coupled in cophasal relation to one another. One end of each of the secondaries is coupled to a respective adjusting resistor which has its movable contact connected via scaling resistors to a respective operational amplifier.
