Description
Technical field
The present invention relates to a kind of wind power generation method, based on the wind power generation method of wind power plant.
Background technique
Wind energy, as a kind of clean renewable energy sources, is more and more subject to the attention of countries in the world.Its amount of accumulateing is huge, and the water energy total amount that the earth can develop also wants large 10 times.Wind is utilized by people very early--mainly to be drawn water by windmill, flour milling etc., and now, people are interested is how to utilize wind to generate electricity.
The kinetic energy of keeping watch becomes mechanical kinetic energy, then is electric power kinetic energy changes mechanical energy, Here it is wind-power electricity generation.The principle of wind-power electricity generation, is utilize wind-force to drive air vane to rotate, then the speed rotated is promoted through booster engine, impel electrical power generators.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 atmospheric pollution.
Device required for wind-power electricity generation, is called wind power generating set.This wind power generating set, can divide wind wheel, generator and steel tower three parts substantially.Wind wheel is the kinetic energy of keeping watch is the vitals of mechanical energy, and it is made up of the impeller of two or more propeller shapes.When wind is to paddle, blade produces aerodynamic force and drive wind wheel to rotate.The material requirements intensity of blade is high, lightweight, and current multiplex glass fibre reinforced plastics or other composite material manufacture.Also have some vertical wind wheels now, s type rotation blade etc., its effect is also identical with conventional helical paddle type blade
Because the rotating ratio of wind wheel is lower, and the size and Orientation of wind-force often varies, and this makes again rotary speed unstabilization fixed; So, before drive electrical generators, also must add the speed-changing gear box that is brought up to rotating speed generator rated speed, then add a speed regulating mechanism and make rotating speed keep stable, and then be connected on generator.For keeping wind wheel to aim at wind direction all the time to obtain maximum power, also need at the tail vane filling a similar wind vane below of wind wheel.
Steel tower is the framework of wind-wheel supporting, tail vane and generator.It generally builds higher, in order that obtain larger and more uniform wind-force, has enough intensity again.Steel tower height looks the situation of ground obstacle to air speed influence, and the diameter of wind wheel and determining, generally within the scope of 6-20 rice.
The effect of generator, being the constant rotational speed being obtained by wind wheel, passing to power facility and evenly operating, thus transform mechanical energy into electricity by raising speed.
Miniature wind power generation system efficiency is very high, but it is not only become by a generator head group, but a mini system having certain scientific and technological content: wind-driven generator+charger+digital inverter.Wind-driven generator by head, turn, empennage, blade form.Every part is all very important, and functions is: blade is used for accepting wind-force and transfers electric energy to by head; Empennage makes blade obtain maximum wind energy facing to the direction of the wind comes from all the time; To turn the function that head can be made to rotate to realize empennage adjustment direction neatly; The rotor of head is permanent magnet, and staor winding cutting magnetic line produces electric energy.
