Thoughts and suggestions on uninterruptible power supply operation and maintenance management of wind turbines

As the main backup power supply of the grid-involved control system of a wind turbine, UPS (Uninterrupted Power Supply) plays a crucial role in the process of fault voltage crossing of the wind turbine. By explaining the working principle of the uninterruptible power supply of wind turbines and combining the case of the off-grid event of wind farm units, the paper analyses the impact of uninterruptible power supply failure on the fault voltage crossing of wind turbines and analyses the technical and management problems behind the off-grid event. It puts forward suggestions on attaching importance to the daily operation, maintenance, investigation, and treatment of the uninterruptible power supply of wind turbines. Promote the healthy operation level of wind farms.
