Design of Excitation Vector Controller of Doubly-Fed Induction Generator Based on TMS320F2812

According to the principle of magnetic field oriented vector control, an excitation vector controller of doubly-fed induction generator based on TMS320F2812 of TI Company is designed. With the analysis of the discipline of active power and reactive power decoupling control, the vector control technology to achieve active power and reactive power decoupling control is used, and the variable speed constant frequency(VSCF) running can be achieved by changing frequency of rotor excitation current. Experimental result shows that the controller can achieve decoupling control and running of VSCF effectively, and has characteristics of simple hardware structure and high reliability and so on.
