Abstract: Systems and methods for maximum deviation multi-phase operation provide techniques for controlling voltage regulators and tap changers in a multi-phase system to operate within a maximum deviation window. The maximum deviation window comprises a low boundary value and a high boundary value. In an example embodiment, systems and methods provide techniques for setting the low boundary value and the high boundary value. In another example embodiment, systems and methods provide techniques for optimized power factor correction in a multi-phase system.

Abstract: A multi-phase control system having multi-phase operation with single phase control includes a main control module, a lineman module, and an add-on lineman module. The main control module and the lineman module control, automatically or manually, the first phase and first phase tap changer of a multi-phase system. The add-on lineman module and the main control module control, automatically or manually, additional phases of the multi-phase system. In certain example embodiments, the multi-phase control system detects when a line voltage of an additional phase is de-energized and allows the tap changer of the additional phase to be powered by a line voltage of the first phase. In certain example embodiments, the tap changer of a de-energized phase is powered by an external power supply.
