Static shunt compensation for voltage flicker reduction and power factor correction

Conference · · Proc. Am. Power Conf.; (United States)
OSTI ID:5274118

It is shown that a static VAR generator comprising a capacitive filter network and a thyristor-controlled inductor can effectively compensate for rapid and unbalanced load variations and is able to maintain system voltage and power factor, even under extremely adverse load conditions. The performance of such a static compensating system is, however, dependent on the principles of control employed, the adequacy of the VAR rating, and the electrical characteristics of the filter network. In arc furnace applications, the VAR generator must be rated for unbalanced load conditions and the capacitive filter network must be designed to be compatible with the ac system impedance, and with the spectrum of the furnace current that contains both odd and even harmonics.
