Method of Smooth Regulation of the Reactive Power with Correction of Quality of Input Current of Thyristor Compensators of the Reactive Power

VOLKOV I. v., CHIZHENKO A. I.

ABSTRACT

The efficiency of using the original method for regulation of the reactive power in the thyristor single-phase bridge source is substantiated. The method is realized by discrete changes following the special algorithm of inductance of the choke inductor in the circuit of direct current. The appropriate quality of the input current is achieved in this way.

KEYWORDS

thyristor reactive power compensator, the method of control, electromagnetic compatibility.
