dc.description.abstract Generation of electricity from the wind is becoming increasing popular as an environmentally responsible resource. Current methods for generating electricity from the wind involve the use of fixed-speed generators. However, the use of variable-speed generators increases the amount of energy that can be extracted from the wind. Most variable-speed technologies require processing large amounts power electronically. In large utility-scale generation systems the added cost of the power electronics may make variable-speed generation too expensive. A reduction in the size of the power electronics is achieved when using the brushless doubly-fed machine. A proof-of-concept system has been developed to evaluate not only the advantages of variable-speed technology, but the advantages of using the brushless doubly-fed machine. The prototype system uses a two-bladed turbine with a diameter of 2.75 meters. The prototype system produces a maximum of 1500 watts in wind speeds ranging from 0 to 40 miles per hour. Experimental data illustrates the performance of the machine over a wide range of power levels. The machine exhibits satisfactory efficiency. Experimental results show that converter rating of the prototype system is one-fifth of that of a conventional variable-speed system. The proof-of-concept system shows that the brushless doubly-fed machine has superior features as compared to other systems. Future research needs to evaluate its use in a utility-scale environment. en_US
