Control of a variable speed and permanent magnet wind turbine: GARBI 150

Abstract

This paper describes the revolutionary new wind turbine GARBI 150. The 150 kW permanent magnet synchronous generator and its full power converter with control in four quadrants make it interesting in medium scale wind power applications. The generator allows direct connection to the electrical distribution grid. The torque and pitch control have been designed to maximize energy capture and minimize fatigue loading of the turbine structure. These controllers are being validated with a first wind turbine prototype. A supervision system has also been implemented.
