Abstract
System for providing electrical power to wind turbine components comprising a busbar, an electrical grid, and an auxiliary power source for selectively providing electrical power to the busbar with an auxiliary power voltage, wherein the main voltage is different from the auxiliary power voltage. The system includes one or more wind turbines comprising a wind turbine generator, a main transformer for connecting the wind turbine generator to the busbar, one or more wind turbine components, and an auxiliary wind turbine transformer. The wind turbine components are arranged to be selectively connected to the main transformer and the busbar through a first path or a second path. The system is configured to select the first path if the voltage at the busbar is the main voltage and to select the second path if the voltage at the busbar is the auxiliary power voltage.
