SYSTEM FOR PROVIDING ELECTRICAL POWER TO A WIND TURBINE COMPONENT

摘要

Systems for providing electrical power to one or more wind turbine electrical components is provided comprising an electrical grid and an auxiliary power source for providing electrical power, and one or more wind turbines. Each of the wind turbines includes a wind turbine generator, one or more electrical components, a main voltage transformer for connecting the wind turbine generator to the grid and a switchgear arranged between the main voltage transformer and a point of connection to the grid. One or more switches for alternately connecting either said electrical grid or said auxiliary power source to the switchgears of the wind turbines are provided. The switchgears comprise a switchgear voltage transformer, the switchgear voltage transformer includes primary and secondary windings, the primary windings receiving power from the electrical grid or auxiliary power source, and the secondary windings delivering electrical power to the wind turbine electrical components.
