Methods and systems for operating a power conversion system

摘要

A power conversion system (14) for providing power to an electrical grid (22) is described. The system includes a power converter (16) coupled to a direct current (DC) power source (12). The system also includes a contactor (24) coupled to the power converter and the electrical grid and configured to selectively electrically couple the power converter to the electrical grid. The system also includes a system controller (18) communicatively coupled to the power converter and the contactor and configured to close the contactor to electrically couple the power converter to the electrical grid and to activate the power converter when a DC voltage provided has remained higher than a voltage level for a length of time. The system controller is also configured to deactivate the power converter, while the contactor is maintained in the closed position, when an alternating current (AC) power output has remained lower than a power level for a length of time.
