Abstract
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.
Claims15
A wind farm capable of quick start up, the wind farm comprising:
- one or more main wind turbine generators (WTGs);
- and
- an auxiliary WTG having a substantially lower start-up energy requirement than any one of the one or more main WTGs,
- wherein 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.
A method for quickly starting up one or more wind turbine generators (WTGs) in a wind farm, the method comprising:
- during an electrical grid outage, preparing one or more WTGs in the wind farm for start-up using locally supplied power before the electrical grid is able to receive and distribute power generated by the wind farm;
- and
- starting up at least one of the one or more WTGs with substantially no delay after the electrical grid is able to receive and distribute power generated by the wind farm.
