The technical principle is based on the air strip theory. The actual calculation can select the section of the vertical fan rotation axis to calculate the model. According to the actual size of the blade, the distance between the rotation axis of each blade is N meters; the calculation of the aerodynamic coefficient is calculated by CFD technology. Principle The discrete digital method is used to solve the aerodynamic forces of the airfoil section. The Reynolds number flow vorticity distribution is compared with the grid method to form the theoretical results of numerical simulation of the Navier-Stokes equation at high Reynolds number.
The principle of using rare earth permanent magnets to generate electricity, wind turbines matching the principle of air hole mechanics, and direct-drive structure for rotary power generation.
Patented technology: a wind generator (patent number: ZL200420081310.2)
Second, the power characteristics According to the principle of H-type wind turbines, wind turbine speed increase speed faster (faster torque rise), and its power generation rate of increase also correspondingly faster, power generation curve becomes full (see below). At the same power, the rated wind speed of the vertical axis wind turbine is smaller than that of the existing horizontal axis wind turbine, and it generates a large amount of power when operating at a low wind speed.
Third, the structure due to this design structure uses a special air hole mechanics, triangle vector method of connection and direct drive structure of the principle, making the wind wheel's stress is mainly concentrated on the hub, so the strong wind resistance; this The characteristics of the design are also reflected in the impact on the surrounding environment. The features of no-noise operation and low electromagnetic interference make the superiority of the new vertical axis wind turbine very obvious.
At present, Japan's production of this type of vertical axis wind power system is the largest in Japan (started in 2002), and the United Kingdom, Canada, and other countries are also currently developing. Most of these countries use parallel connections in the design of wind turbines. Rod, this method requires a higher output shaft of the generator, and the structure is relatively complicated, and the on-site installation procedure is also high. In addition, from a mechanical point of view, the greater the power of the H-type vertical axis wind turbine and the longer the blade, the longer the distance between the center point of the parallel rod and the center point of the generator shaft, the weaker the wind resistance, therefore, the MUCE takes The triangular vector method compensates for some of the above shortcomings.
