This works presents the development of a testrig for wind turbine emulation, including the conversion system from wind to electrical energy. The complete emulation test-rig has a driving element, in charge of providing the torque/speed profiles, corresponding to real data of wind availability in a given geographical location. The driving element, in this case a 3.3 kW DC machine, is coupled to the generator, in this work a 4.0 kW @ 50 Hz double feed induction generator (DFIG). Both electrical machines are feed from power electronic converters, an H-bridge for the DC machine, and a dual three-phase converter for the induction machine. The switching elements in these converters are insulated gate bipolar transistors (IGBT). Two heat-sinks are used for the power electronics, one for a rectifier/H-bride feeding the DC machine, and the other for the dual converter. The speed at the common shaft is measured using an optical-encoder. The control signals, for the emulator, are measured using two sensor cards, providing up to 16 signals between currents and voltages. Both converters are controlled from a DSP based board coupled to an FPGA board, providing the high amount of processing power required by the different control techniques. The converters are controlled using pulse width modulators with adjustable carrier frequency, for this work a 10 kHz carrier is selected.
