Abstract
In a typical power system, a motor bus is fed by a main power system; and, an auxiliary system is provided to alternatively feed the motor bus. When a fast transfer from the main power to the auxiliary power system is desired, for example, in case of fault occurring in the main system, the inventive method transfers power in a synchronous mode; that is, power is transferred from the auxiliary system to the motor bus when the phase difference of the auxiliary system with respect to the frequency of the residual voltage on the motor bus is essentially zero degrees.
