DSP based Emulator for Wind Power Generation Systems

A DSP based Wind Turbine Emulator System is presented. It consists on two-levels software and a workbench of two electrical machines. A high level software (called WindTE®) have been developed for a PC, in a MsWindows style. This software presents the wind to the system and carry out control algorithms for optimal control of maximum wind energy extraction and sets the work-point of the Wind Turbine. A low level software integrated in a DSP develops the vector control of AC generator current and sets the work point of the power electronics. A set of two coupled electrical machines emulates the complete Wind Generator system. An AC induction motor acts as a generator which is feed by a DC machine acting as the Wind Turbine and emulating the wind profile presented by the high level software WindTE. The generator is connected to the grid using IGBTs, so it is possible to emulate many types of Wind Power Generation System, scalled to the mechanical system used.
