CPC G05F 1/147 (2013.01) | 20 Claims |
1. A control system for a multi-phase power system including a first phase line, a second phase line, and a third phase line, the control system comprising:
a plurality of regulator controls including,
a first regulator control configured to control a first tap changer associated with the first phase line;
a second regulator control configured to control a second tap changer associated with the second phase line;
a third regulator control configured to control a third tap changer associated with the third phase line;
a converter circuit configured to convert power flowing through the first, second, and third phase lines to levels used for powering the first, second, and third tap changers; and
an electronic processor coupled to the first regulator control, the second regulator control, and the third regulator control, the electronic processor configured to:
determine whether a voltage level of the first phase line exceeds a threshold;
control a first relay to power the first tap changer with power converted from the first phase line to affect a tap change on the first phase line when the voltage level of the first phase exceeds the threshold;
determine whether a voltage level of the second phase line exceeds the threshold when the voltage level of the first phase line is less than the threshold; and
control a second relay to power the first tap changer with power converted from the second phase line to affect a tap change on the first phase line when the voltage of the first phase line is less than the threshold.
