8 INTRODUCTION The wind energy generator uses a rotor (blades), a power shaft and a generator to convert the wind's kinetic energy into electrical energy. When wind passes over the rotor, it creates aerodynamic lift that causes the rotor to spin. This rotary motion is used to drive the generator and produce electricity. Wind turbines are also equipped with a rotor control to adjust spin rate and stop the motion of the blades. Because wind speed increases with height, wind turbines are mounted on towers. The amount of energy a wind turbine produces depends on wind speed and the diameter of the rotor. To be considered a good location for wind energy, an area needs to have average annual wind speeds of at least 12 miles per hour. PRODUCT SPECIFICATIONS Rotor Blade Profiles The thick profiles in the innermost part of the blade, however, are usually designed specifically for wind turbines. Choosing profiles for rotor blades involves a number of compromises including reliable lift and stall characteristics, and the profile's ability to perform well even if there is some dirt on the surface (which may be a problem in areas where there is little rain). Rotor Blade Materials Most modern rotor blades on large wind turbines are made of glass fiber reinforced plastics, (GRP), i.e. glass fiber reinforced polyester or epoxy. Tower The tower on which a wind turbine is mounted is not just a support structure. It also raises the wind turbine so that its blades safely clear the ground and so it can reach the stronger winds at higher elevations. Maximum tower height is optional in most cases, except where zoning restrictions apply. The decision of what height tower to use will be based on the cost of taller towers versus the value of the increase in energy production resulting from their use. Studies have shown that the added cost of increasing tower height is often justified by the added power generated from the stronger winds. Larger wind turbines are usually mounted on towers ranging from 40 to 70 meters tall. Power Shaft 8

9 Low Speed The low speed shaft of the wind turbine connects the rotor hub to the gears. On a modern 600 kw wind turbine the rotor rotates relatively slowly, about 19 to 30 revolutions per minute (RPM). The shaft contains pipes for the hydraulics system to enable the aerodynamic brakes to operate. High Speed The high speed shaft rotates with approximately. 1,500 revolutions per minute (RPM) and drives the electrical generator. It is equipped with an emergency mechanical disc brake. The mechanical brake is used in case of failure of the aerodynamic brake, or when the turbine is being serviced. Generator The generator is what converts the turning motion of a wind turbine's blades into electricity. Inside this component, coils of wire are rotated in a magnetic field to produce electricity. Different generator designs produce either alternating current (AC) or direct current (DC), The generator's rating, or size, is dependent on the length of the wind turbine's blades because more energy is captured by longer blades. It is important to select the right type of generator to match your intended use. Most home and office appliances operate on 120 volt (or 240 volt), some appliances can operate on either AC or DC, such as light bulbs and resistance heaters, and many others can be adapted to run on DC. Storage systems using batteries store DC and usually are configured at voltages of between 12 volts and 120 volts. DC generators are normally used in battery charging applications and for operating DC appliances and machinery. They also can be used to produce AC electricity with the use of an inverter, which converts DC to AC. Electrical Storage Box Batteries are the most common form of electrical storage. Batteries can store and deliver only DC power. Unless an inverter is used to convert DC to AC, only DC appliances can be operated from the stored power. The battery voltage must be the same as the voltage needed to run the appliance. 9

10 Installation, Maintenance and System Life Wind turbines should be installed by qualified, experienced people. Local codes should be checked to determine if contractors must be licensed. The local building inspector may be required to inspect the completed work. For utility interconnected systems, a utilitydesignated inspector probably will make an inspection. By their very nature, wind turbines are subject to extreme physical forces. The tips of a wind turbine rotor can reach speeds of up to 300 mph. Hail, dirt and insects contacting the blades at these speeds can cause wear to the blade edges. Bearings that support the rotor or other moving parts are also subject to wear. The lifetime of these bearings depends on the wind conditions and level of maintenance care. The entire wind system, including the tower, storage devices and wiring should be inspected at least once a year. Routine maintenance might include changing the transmission oil, greasing the bearings and visually inspecting the condition of the blades, tower and electrical connections. Instead of doing the maintenance work yourself (which may require climbing the tower), you can arrange a maintenance contract with the dealer. 10
