From natural sources we derive, among other things, lighting and heating, and those are the factors which keep the whole economy working. In some states water power forms the basis for natural energy. In other states, like California for instance, wind power is the natural energy source. Actually, the California wind means that millions of kilowatt hours are floating about in the air, so really, it is only a question of harnessing them. The advanced Wind Matic windmill renders this possible through an invest- ment which is not only financially profit- able, but also an extremely solid way to save energy money. In areas which are particularly wind-swept it would be almost unwise not to utilize the wind energy. Wind Matic WM 17 S means a safe investment in the future Here are some facts which speak for investing in windmills Wind power: The investment. It would be an understatement to say that wind power represents a favorable investment opportunity. In fact, thanks to several factors, wind power is one of the most attractive investment opportunities ever offered to the private investor. Wind power is ,pre -sold ,. Federal and state law require utility companies to pur- chase all the power that wind generation can produce. That means that every single watt of wind -produced electricity is guaranteed a market! Better still, the utili- ty companies are required to purchase wind -generated power at the ,highest avoided cost- - that is, the maximum rate they would have to pay for conventionally - produced power. Here are some facts which speak for investing in Wind Matic Wind Matic A/S has more than 10 years experience in development and production of windmills and is the Danish company which has the best knowledge in this field. The Wind Matic windmill occupies a prominent position because of the advanced technology and design of the windmill and because the cornpo- nents used are of high quality. All factors which ensure a reliable, effective opera- tion and a very long life, including very little maintenance. YRT� The result of many years of research and development The Wind Matic 17 S has been devel- oped on the basis of the WM 15 S. The Wind Matic 17 S is the latest devel- opment in our S-series and thus it is con- structed with the purpose of obtaining a higher power output. The WM 17 S is equipped with advanced computer steer- ing, based on micro -processor techno- logy. The annual energy yield of the windmill is dependent on the wind conditions of the site in question and of course the plac- ing of the windmill. The power of the WM 17 S can be read from the power curve below.

The turbine is mounted on a forged shaft, supported by two heavy-duty, spherical roller bearings. 2) When designing the aerofoil empha- sis was placed on obtaining a higher power output. The blades are made of fiberglass reinforced Polyester, built up around a reinforced main beam with an imbedded root of heat -treated SG -iron. 3) Each blade is equipped with a spoil- er type independent aerodynamic brake, providing a secondary braking system. Sturdy quality down to details The hub is a welded, heavy-duty construction, bolted to the flange on the main shaft. MW NOW The windmill is equipped with an operation brake on the slowrevolving shaft. A fact which means that the gearbox will not be exposed to large mechanical loads when breakina. The nacelle rotates on four self - greasing Oilon blocks, mounted between the cabin and the yaw gear wheel. Between the gearbox and the generator a flexible coupling, free of maintenance, is mounted. The yawing system functions by means of a yaw motor and a yaw gear which keeps the windmill oriented to the wind direction. The yaw motor is controlled by means of wind vane signals. CMTQ( ha-s built-in electronic supervision, providing maximum security The control system of the WM 17 S is based on advanced microprocessor technology. The system supervises and controls both the grid and the windmill and will bring the windmill to an immediate halt if any irregularity should arise: 1. Abnormal variations in grid frequency and grid voltage. 2. Overspeed on main and/or generator shaft. 3. Transmission error between large and small generator. 4. Breaking of phase between large and small generator. 5. Thermal overload of generators (tem- peratures measured on two levels). 6. Thermal overload of yaw motor. 7. Thermal overload of gearbox. 8. Abnormal vibrations. 9. Max. yawing period exceeded. 10. Level too low in brake fluid reservoir. 11. Oil level too low in gearbox. 12. Worn brake blocks. 13. Abnormal twisting of cables (automatic un-twisting). Technical specifications WM 17 S 14. Wind speed higher than cut-out speed. When the points stated in 13 and 14 are corrected, the computer control will re -start the windmill automatically. Thyri- stor control from the computer ensures a careful, soft connection to the grid. A display on the control panel indicates any irregularity by the windmill operation or by the grid. Also, other factors such as wind speed, electric power, and the RPM, will appear from the display. This control system also gives you the possibility of connecting a computer for central super- vision.
