Method of smooth controlling the reactive power in the electrical network using a thyristor reactive power compensator is proposed. Smooth control is carried out under a load by switching taps inductive reactor coils. Significant improvement in the quality of the input current is accomplished by reducing higher harmonics therein levels. References 3, figures 4, tables 2.
Key words: network, thyristor reactive power compensator, regulation of reactive power, switching taps, inductive reactor coils, power quality, current harmonic distortion.
