| description | A system and method are provided for operating a power generating asset electrically coupled to a power grid. The power generating asset includes a power converter having a line-side converter operably coupled to the power grid via a converter contactor. Accordingly, a line-side converter of the power converter is decoupled from the power grid and a controller determines the phase angle of the grid voltage. A switching sequence for a plurality switching devices of the line-side converter is then set in order to develop a pre-charge voltage phase angle at a converter-side terminal of the converter contactor which is in phase with the phase angle of the grid voltage. A portion of the charge of the DC link is then discharged through the line-side converter to develop a pre-charge voltage at the converter-side terminal. Once the in-phase, pre-charge voltage is established at the converter-side terminal, the converter contactor is closed to re-couple the line-side converter to the power grid. |
