Abstract: Currently, given technical-economic and especially environmental aspects, it is important to supply electric power, in a distributed environment, through wind generation where the resource allows it. With the above purpose, in this work, a low power wind turbine, in this case 50 kW, with modeling of wind energy conversion (WECS) for synchronous generator with permanent magnets is modeled and simulated with Simulink ^ ® by Matlab ^ ®. (PMSG) of non-salient poles, direct coupling (Gear Less), variable speed and variable blade pitch. It uses a control scheme to capture maximum wind energy (MPPT, in partial load zone), which applies to the PMSG a setting of the stator direct current to zero amperes (ZDC control). On the other hand, it uses a conversion technology (back to back) in two levels, with vector modulation, and active and reactive power control to the grid using a VOC (voltage-oriented control) in closed loop. Most important simulation outcomes are presented, for specific working conditions, whose performance analysis justifies the current development of the experimental conversion prototype that validates them.
