80 KW VERTICAL AXIS MACHINE FOR ELECTRICITY PRODUCTION ON SKYROS ISLAND

Ziel

A vertical axis wind turbine of 80 KW, will be constructed, installed and tested in connection to the autonomous diesel based electricity grid of the island of Skyros, in order to develop greek technology in the field of design and manufacture of 80 KW wind machine, under competitive economical conditions and to demonstrate and prove the economic viability of such units as well as their capability to operate and perform according the designed specifications. Estimated annual yield at the site of installation : 210 MWh.

A vertical axis, Darrieus-type, 2 bladed wind turbine with rated power 80 KW will be designed, constructed and installed on the island of Skyros, Greece, in order to gain experience and demonstrate the economic viability of such units and their operation and performance according to their design specifications.The rotor height is 16m and the diameter is 20m. The 2 blades of the rotor will be from extruded aluminium. The 20m rotor axis will be from stainless steel in three pieces and will be supported through three guy wires. The gear box will be of special construction with ratio 1:29.7. The asynchronous 80 KW generator will be connected to the 2.5 MW diesel based grid of the island. The cut-in speed is 4.7 m/s and the cut-out 25 m/s. The estimated annual yield is 210 MWh which corresponds to a fuel saving of 46 tons/yr.
The esimated cost per unit of Aeolian KWh is 14.06 DRA while the conventional one is 21.6 DRA. During the demonstration phase which will last 2 years it will be possible to evaluate all the figures of this new design. It is a cooperative project between the Public Power Corporation (PPC) and the National Technical University of Athens (NTUA), which will cooperate with BIEX, METKA, and the Hellenic Aerospace Industry (HAI) which will be mainly responsible for the construction and the spare parts.
The machine will be installed for comparison reasons next to a horizontal axis 80 KW machine. For the latter one see project WE/626/84/HE.
