METHOD FOR SAFE ISOLATION AND RECONNECT OF GRID GENERATION DEVICES TO ENERGY STORAGE OR ALTERNATE GENERATION REFERENCE

摘要

Power control circuitry, power systems, and related methods are disclosed. A power system includes power control circuitry including a first power switch configured to couple a supplemental grid-synchronized power generator to a main grid power source, and a second power switch configured to couple the supplemental grid-synchronized power generator to a distribution unit configured to distribute electrical power to loads. The power control circuitry also includes time delay circuitry configured to control the first power switch and the second power switch. A method includes maintaining a supplemental grid synchronized power generator coupled to a main grid power source while main electrical power is provided thereby, and decoupling the supplemental grid synchronized power generator therefrom responsive to a cease in the main electrical power. The method also includes coupling the supplemental grid synchronized power generator to a distribution unit a delayed period of time following a cease in the main electrical power.
