A wind turbine emulator based on a dual DSP processor system

In this paper the principles and structure of a wind turbine emulator (WTE) are described. The WTE is a versatile system specially designed for the purpose of developing and testing new control strategies for wind energy conversion systems. The WTE is built around a processor module, which controls a separately-excited DC motor. The core of the processor module is a dual DSP system working in a tightly-coupled architecture. The WTE provides a friendly environment to readily modify wind speed conditions, change turbine parameters and supervise system variables. Experimental results from the WTE coupled to a grid-connected induction generator are analyzed.
