PROJECT TITLE :
Developing a New SVPWM Control Strategy for Open-Winding Brushless Doubly Fed Reluctance Generators
ABSTRACT:
During this paper, a replacement open-winding control strategy is proposed for a brushless doubly fed reluctance generator (BDFRG) used for stand-alone wind turbine or ship generators. The BDFRG is characterised with 2 windings on the stator: an influence winding and a control winding. The management winding is fed with twin two-level 3-part converters, and a vector control scheme based mostly on space vector pulsewidth modulation is meant. Compared with ancient three-level inverter systems, the dc-link voltage and the voltage rating of power devices in the proposed system are reduced by 50% whereas still greatly improving the reliability, redundancy, and fault tolerance of the proposed system by increasing the switching modes. Its performance is evaluated by simulation in MATLAB/Simulink and an experimental study on a forty two-kW prototype machine.
