Abstract
The present disclosure pertains to systems and methods for using time synchronized measurements of a generator output and an electrical bus, together with generator control algorithms to synchronize the frequency, voltage, and phase of a generator, or group of generators, prior to electrically connecting the generator to the electrical bus. More particularly, but not exclusively, the present disclosure pertains to systems that may be operated in an islanded configuration and in which one or more generators may be selectively synchronized based on a common time reference. The common time reference may allow the generators to be synchronized by autonomously driving one or more generators to a specified phase angle and frequency.
