US Patent 11509141 Wind turbine power consumption control

A power management module and method for controlling power consumption of consumers in a wind turbine system. Each power management module in the wind turbine system is configured to determine a voltage level of a power supply bus of the wind turbine system and then control a level of power consumption of one or more consumers coupled to the power supply bus based at least in part on the determined voltage level of the power supply bus. Power consumption may thereby be managed throughout the wind turbine system, without requiring a dedicated centralised controller and communications infrastructure.
