Application field

Supercapacitor-fan pitch backup power supply

Provide a series of all-weather module solutions, as the backup power supply of the wind turbine pitch control system, which improves the reliability, safety and maintenance-free of the pitch power supply

high pressure system

Use 75V/85V/90V/150V/160V modules, series and parallel to meet the needs of different voltage levels and different capacities.

low pressure system

For fans with different powers, use different numbers of 16V modules in series, or use 80V modules directly.

Application principle

The supercapacitor replaces the battery as a backup power supply for the wind turbine pitch system. Usually, the electric energy generated by the fan is input into the charger through the grid power supply, and the charger charges the supercapacitor energy storage power supply until the supercapacitor energy storage reaches the rated voltage.

When it is necessary to adjust the pitch of the wind turbine, the control system generates an instruction, the supercapacitor energy storage system is discharged, and the pitch system is driven to work.
