OPERATING EXPERIENCE FROM THE EHECATL WIND TURBINES

This paper presents a summary of the mechanical features and the mediu m term operating experience from three small horizontal axis wind ener gy conversion systems covering a range of 500 to 5000 Watt, intented f or rural and isolated communities. These turbines have a new regulator which reduces gyroscopic loads, is easy to adjust and could be manufa ctured stronger and in smaller sizes than the conventional tail vanes. It is concluded that is feasible to build cheaps and reliable wind tu rbine generators with an acceptable efficiency employing common-use el ements, but is needed a careful and optimized design.
