Fixed pitch wind turbine emulator using a DC motor and a series resistor

It is presented a novel emulator for fixed pitch wind turbines, allowing the laboratory testing of the generator control systems associated with the turbines. The emulator consists of the coupling in series of the following elements: a source of DC voltage, a power resistance and a DC motor. The modification of the input DC voltage has the same effect as the variation of wind speed in a fixed pitch wind turbine. It is included the theoretical foundation of the emulator, the simulations and the experimental results.
