Abstract
This is a continuous work on the project of a doubly-fed permanent magnet (DFPM) generator for wind turbines. The construction of a prototype machine was finally finished and experiments were conducted to verify the design of the DFPM machine and to establish a basis for designing more powerful machines in industry usage. In the thesis, a finite element model of the machine is established, from which the parameters of the prototype machine are estimated. Then the experiment data are compared with the estimated values to verify the model of the machine. At last a vector control method is proposed with the stability analysis using the parameters developed from the model. Moreover, the damping effect of the permanent magnet (PM) rotor plate is explored. Keywords: doubly-fed induction, permanent magnet, finite element, open circuit, v-curve, damping coil, vector control, sensorless.
