The principle of wind-power electricity generation briefly is to see through the wind energy rotor blade, converts wind energy into mechanical energy, and utilizes generator to convert mechanical energy into electric energy, utilizes storage battery with energy storage again.So wind-driven generator mainly comprises wind wheel and generator two large divisions.Wind wheel can be divided into horizontal and rectilinear according to the relative position of its main shaft and horizontal plane.
Many experiments and research show that under the condition that the wind wheel blowing area equates, the wind energy utilization of horizontal wind wheel is about about 23% ~ 29%, and rectilinear can reaching more than 40%.Aspect starting wind velocity, the starting performance of horizontal wind wheel well has been present common recognition, and the starting performance of vertical shaft is relatively poor comparatively speaking, but if improvement design is suitable as long as aerofoil profile and established angle are selected, then can improve this problem.Aspect structural feature; The blade of horizontal wind wheel is in the process that rotates a circle; Receive the comprehensive function of inertial force and gravity, the direction of inertial force changes at any time, and the direction of gravity is then constant all the time; What blade was suffered like this is exactly an alternate load, and this fatigue strength to blade is very disadvantageous.The generator application of horizontal wind wheel is strong in wind-force, and therefore the field domain that wind speed is fast all places tens meters high-altitude, and this makes the installation and the very inconvenience of maintenance of generator.The blade of vertical axis rotor stressing conditions in the process of rotation is more much better than horizontal axis; Because the direction of inertial force and gravity is constant all the time; Suffered is a permanent load, so fatigue life is longer than horizontal, simultaneously; The generator of vertical shaft can be placed on the bottom or the ground of wind wheel, is convenient to installation and maintenance.

Based on above analysis, the advantage of rectilinear wind wheel is more than horizontal, and the application of wind-driven generator is also comparatively wide.
Based in the prior art for the relatively argumentation of horizontal and rectilinear wind wheel, under the more situation of the niche condition of rectilinear wind wheel, the claimant sets about researching and developing the improvement of rectilinear wind wheel, particularly wind energy utilization and these two parts of starting performance.
