Abstract: Systems and methods for maintaining the active power production of a fluid turbine and regulating the temperature of an electrical generating component by controlling the reactive power production are disclosed. A thermal parameter of the electrical generating component is monitored. If the electrical generating component exceeds a thermal parameter the reactive power production of the turbine is reduced. A fluid turbine may be de-rated to further reduce an electrical generating component's thermal parameter. A fluid turbine may shut down to further reduce an electrical generating component's thermal parameter. A fluid turbine's power production is re-started when the electrical generating component returns to an acceptable thermal parameter.

Abstract: One or more variable pitch airfoils in fluid communication with a rotor of a fluid turbine can control the amount of energy directed to the rotor, and further control the amount of energy generated by the turbine. Varying the pitch of the airfoils may provide a means of controlling the power output of a fluid turbine without the need to control the pitch of the rotor blades, and may further provide a means of mitigating the effects of wind shear on the rotor. Variable pitch airfoils may also include a means of controlling the active power, reactive power and SCADA, of a group of fluid turbines.
