At the General Assembly of the European Geophysical Union held in Vienna, Austria, in April 2007, Mike Rose of the British Antarctic Survey presented the paper "Variable speed wind generator control in Antarctica." Beginning with some tutorial information on wind generators, the paper presented an approach to controlling rotor speed to maximize power generation will also preventing the generator from entering a high speed runaway condition. The PWM approach, also known as Electro-Dynamic Braking, is presented as being superior to resistive loading. It is generic to many manufacturer models and it is readily scalable to wind generators of higher output. The heat generated by the shunt element can be used to heat a battery pack associated with the wind generator system, improving storage capacity.
