Quick start-up of wind turbine generators

摘要

A wind farm is provided that is capable of quickly starting up without delay after an electrical grid becomes available after an outage. According to one embodiment, the wind farm comprises one or more main WTGs and an auxiliary WTG having a substantially lower start-up energy requirement than the one or more main WTGs. The auxiliary WTG is coupled to supply power to the one or more main WTGs to prepare the one or more main WTGs for start-up.

主权项

1. A wind farm capable of quick start-up, the wind farm comprising:
one or more main wind turbine generators (WTGs) configured to supply power to an external electrical grid; an auxiliary WTG having a substantially lower start-up energy requirement than any one of the one or more main WTGs; and a control arrangement coupled with the one or more main WTGs and the auxiliary WTG, the control arrangement configured to:
initiate a shutdown process of the wind farm in response to an unavailability of the electrical grid, andstart up, before power production from at least a first main WTG is ceased as part of the shutdown process, the auxiliary WTG using power supplied directly from the first main WTG to the auxiliary WTG, wherein the auxiliary WTG, when started up, is configured to supply power to at least one of the main WTGs to prepare the at least one main WTG to be started up when the electrical grid subsequently becomes available.
