Domestic small wind power technology in the "low wind start, low wind speed generation, pitch moment, multiple protection, and a series of technical attention by the international market and international clients is to meet the electricity from wind power generating capacity to measure the cost of solar energy economy than many 。     

     Wind, solar and wind power integration advantages, not only for the "energy saving, emission reduction,"opened up new horizons for the application of science to meet human needs, for the world to open a fourth Revolution。

     Second，Wind power has three kinds of operation mode:

     one is independent operation mode, usually a small wind generators to one or a few 

families to provide power, storage battery energy, to ensure the electricity without wind, Second is the wind turbines and other power mode (such as engine power), combining to unit or an village or an island power supply, Three is wind power into conventional power operate and to provide electric power grid, is often a wind tens or hundreds of sets installed wind generators, this is the main development direction of wind power。     

     Wind power system in the two main parts is wind machine and generators。 Wind turbines to change from adjusting technique, plasma generator toward VSCF technology, this is the development trend of wind power technology is the core technology nowadays wind turbines。 The following simple introduction of this two respects。     

     the change of wind plasma from regulation     

     Wind turbines impeller, will capture the wind by converting wind effects on the mechanical wheel torque。     

     Change is the change from adjustment with vertical axis wind leaf surface of Angle, thus affecting the force and the blade, when the wind resistance increases, the output power of the fan is kept constant power output。 By regulating mode, fan from the output power curve is smooth。 In the rated wind leaf Angle of attack,controller will be placed near zero, do not change, approximate distance equal to adjust for pulp。 In the rated wind above, variable structure control function from pulp, adjust the blade Angle of attack, the output power control in near ratings。 Change from the wind plasma starting from wind speed is set slurry machine downtime at low impact stress relative ease。 The normal work, is mainly adopts power control, in practical applications, power and speed is directly proportional to the set。 Small changes will cause the wind changes of wind。     

     Due to the change of wind from pulp by adjusting the impact than other wind from small, can reduce material utilization rate, reduce overall weight。 And the change of wind from accommodation type at low speed, can make the blades, keep good Angle of attack than accommodation type stall wind turbines have better energy output, therefore is suitable for low average speed of the region。     

     Change from another advantage of regulation, when the winds reach a certain value, stall type of wind and downtime, must from type machine can gradually changes to the wind load without a blades of open mode, avoid wing, increase of wind turbine。     

     Change is to adjust the defect is sensitive response requires gusts。 Because the wind accommodation type  stall fan vibration power pulse are small, and accommodation type from wind turbines is bigger, especially for the change from the constant speed windmills way, this kind of circumstance, this does not require more obvious change in the fan is the response speed of wind system to fast enough, can reduce this phenomenon。 风力发电技术的英文文献和中文翻译(2):http://www.youerw.com/fanyi/lunwen_87327.html
