Supply And Distribution Of Alternating Current
(AREA)
Abstract
A method for automatic switching-on backup supply of consumers comprises measurement of currents and voltages of a direct sequence of buses of the main and backup power sources, measurement of an angle between voltage vectors of the direct sequence of buses of the main and backup power sources. Additionally, an angle between the vectors of current of the same phases at input of the main and backup power sources is measured.
