Abstract
In a power generation system that includes a ram air turbine that drives an electric generator and at least one electric bus that couples alternating current electric power from the electric generator to at least one electric load, a method of maintaining the speed of the ram air turbine within a desired range of speeds that comprises the step of uncoupling the at least one electric bus from the electric generator when the frequency of the alternating current falls under a desired minimum frequency.
