Wind Power: Talk 1
• Why wind? • How wind turbines
work • The power in the
wind
Key factors in wind power
• Wind consistency (how much of the time does the wind blow, at a useful speed?)
• Wind speed (how high is the average wind speed?) • Spacing of turbines in the array (are they far enough apart to
require yaw device
• Vertical axis
– Don’t need to point into the wind
– Easy to construct
– Less efficient – Mounted lower, less
wind – More turbulent, stress
access undisturbed wind?) • Size of turbines (how large is the area of e circle covered by
the blades?) • How large an area of land (or sea) can be dedicated to the
Why wind?
• Wind is widely available • Largely independent from imports,

The shortcomings of hytro- power
Water to drown large areas of land, may lead ecological to __________ destruction and if the large _________ once collapse, the consequences reservoirs would be disastrous. In addition, a country's water resources are limited, but also by the impact of the season.
索耶表示，目前风力发电仅占美国电力市场的2%。随 着电网升级，到2030年风能的市场份额将上升20%甚至 更多。 For the U.S., Sawyer said, upgrades to the electric grid could help raise wind power’s share from about 2% of total electricity today to 20% or more, by the year 2030. 史蒂夫•索耶：我们国家拥有丰富的电力资源，从这个 角度来看，供电是不成问题的。然而真正的挑战在于 如何有效利用这些资源，充分保证电力市场的供应 Steve Sawyer: You could supply the whole country with electricity, no problem, in terms of the raw resource. But we have to actually capture that and then get it to the markets. That’s the challenge.

3.1 classification
• Generally, wind turbines can rotate about either a horizontal or a vertical axis, the former being both older and more common. They can also include blades (transparent or not)or be bladeless.
3.3 the Yaw System
There are many methods. Here are some simple examples.
• In medium and large wind turbine generator systems, electrical yaw systems are used widely, which are of higher accuracy and reaction velocity. The core part of the yaw system is a servo motor, which makes sure that the spades face the largest rotor swept area. The indicator rotates according to wind direction and transmits the angle value to a sensor. Then a AC contactor is on and the servo motor works, adjusting the orientation of rotating plane of spades. When that deviation is erased, a limit switch is off and the servo motor stops.

Traditional energy and electricity generation
Although there are many different sources of energy available, more than three-quarters of the energy used in developed countries comes from oil, gas and coal. Currently the thermal power plants of our country, which take up more than 70% of the installed capacity of China’s electrical power system, use coal as fuel.
