The Research on the Braking System of the Small Danielle Wind Generators

By researching on the mathematical model of small danielle wind generators, it is easily to find that reasonable load connection and disconnection or changing the load characteristics could control the rotational speed and output power of wind generators. Using the controlling strategy combined with switching braking resistor and three-phase short-circuit braking, the rotational speed of wind generator could be controlled accurately in the scenes of sustainable strong wind or the wind speed continuously increasing. At the same time, users' cost could be ensured. A lot of field experiments had proved the feasibility and practicality of the controlling strategy. The research of this paper would promote the application of small danielle wind generators.
