Description
Technical field
The present invention relates to wind turbine blades to lengthen technology, and in particular to a kind of wind turbine blade blade tip extends dress
It puts and method.
Background technology
The generating efficiency of wind turbine is an important factor for each wind power plant is considered, and how to improve each wind as far as possible
The generating efficiency of power turbine is that those skilled in the art are needed to be considered when establishing wind power plant.Wherein influence wind turbine
, such as the wind-resources distribution situation of wind power plant, the configuration of wind turbine and the wind-force whirlpool many because being known as of machine generating efficiency
The parameter setting of turbine blade and the matching degree of wind turbine etc..
In practical applications, although having given the considerations of abundant when establishing wind power plant, some wind power plants still have wind
Resource situation and the unmatched situation of wind turbine so that the generating efficiency of wind turbine cannot be played effectively, particularly
When wind power plant annual mean wind speed is relatively low, wind turbine electric generation amount is less, and wind power plant economic benefit reduces, and to improve wind-force whirlpool
The generating efficiency of turbine must then re-start wind turbine the configuration in structure or size.
Pass through the extension to wind turbine blade blade tip so that wind turbine obtains the wind sweeping area of bigger, can be with
The generating efficiency of wind turbine is improved, increases the income of wind power plant.It has existed in the prior art a variety of to wind turbine
Blade tip extends or the method and apparatus of lengthening, is mostly by original wind in these known lengthened vanes technologies
