How to operate a wind turbine during grid loss using a power storage unit

摘要

The present invention relates to a method of operating a wind turbine using a power storage unit, such as a rechargeable battery, to power a group of power consuming units during grid loss. The wind turbine includes a plurality of power consumption units grouped into at least a first group and a second group, a first electrical converter for connecting the generator to the electrical grid, and a second electrical converter for connecting the generator to the power storage unit. do. Upon detecting the occurrence of grid loss, the generator is operated to ensure sufficient power of the power storage unit to operate the first group of power consuming units.
