Adaptation of Floating Point DSP-Based Technology for Small Variable-Speed Wind Turbine

In this article we present the design and development of a control board that uses of two floating point digital signal processors to control a double converter inside a small wind turbine induction generator. The algorithms programmed on the processors have the ability to perform a vector control over the transient torque on the generator, controlling at the same time the flux of active and reactive power supplied to the network. Bearing in mind that requirements for robustness and maintenance reduction are a must when designing a micro wind turbine generator, the developed control system eliminates the need for position and shaft speed sensors and greatly reduces the size of the filter in the network connection.
