Wind turbine emulation using permanent magnet synchronous generator

This paper aims to presents the results obtained in electromechanical wind speed emulator of distributed low power system. The results are obtained in insulated regime with a step up/down converter, battery bank and resistive load. All the operating regions are aimed, namely optimization and power limitation one, and also an intermediate operating region is considered in order to ensure smooth transition between these two regions. For control purpose an improved strategy is proposed. Hardware implementation is done under DS1103 controller board running under Matlab and ControlDesk (R) software. This paper present results from a functional low power wind system, part of a distributed multisource low power system, which offer also the possibility of implementing the behavior and the control of such systems, in grid-connected or disconnected from the national grid. Experimental results show the effectiveness of the proposed system under various conditions.
