Description

A kind of power of fan prediction unit
Technical field
The utility model relates to a kind of power of fan prediction unit of power industry.
Background technology
Wind is the new forms of energy that a kind of potentiality are very large, 18 beginnings of the century, sweep away the once violent strong wind of two countries of Great Britain and France, wipe out 400 wind-force mills, 800 houses, 100 churches, more than 400 sailing boat, and having thousands to come to harm, large tree is uprooped in 250,000 strain.The only opinion with regard to pulling out tree, wind has just sent 10,000,000 horsepowers (7,500,000 kilowatts within the several seconds; One horsepower equals 0.75 kilowatt) power have people to estimate, on the earth, can be used to generating wind resource approximately have 10,000,000,000 kilowatts, be almost 10 times of present whole world hydropower amount.The energy that at present the annual coal combustion in the whole world obtains, only have wind-force in 1 year the energy that provides 1/3rd.Therefore, all take much count of both at home and abroad utilizing wind-force to generate electricity, tap a new source of energy.
The kinetic energy of keeping watch is transformed into mechanical kinetic energy, then mechanical energy is converted into electric power kinetic energy, Here it is wind-power electricity generation.The principle of wind-power electricity generation, is to utilize wind-force to drive air vane rotation, then sees through booster engine by the speed lifting of rotation, impels generator generating.According to current windmill technology, be approximately the gentle breeze speed (degree of gentle breeze) of three meters per second, just can start generating.Wind-power electricity generation forms one upsurge just in the world, because wind-power electricity generation does not need to use fuel, also can not produce radiation or air pollution.
