Wind power generating set with vertical shaft

Abstract

The invention discloses a wind power generating set with a vertical shaft. The wind power generating set comprises an electric generator, a system bracket, a vertical shaft, a blade bracket, a group of lift-type blades and a group of resistance-type blades, wherein the lift-type blade and the resistance-type blades are uniformly arranged on two peripheries with different diameters by taking the vertical shaft as a centre respectively; the lift-type blades are arranged on the outer periphery; the resistance-type blades are arranged on the inner periphery; and a centrifugal speed stabilizing controller used for automatically adjusting the windward area of the resistance-type blades is also arranged at the top of each resistance-type blade. The wind power generating set can take advantage of lift and resistance at the same time to normally generate electricity at a low wind speed; and when the wind speed is increased, the centrifugal speed stabilizing controller can rotate the resistance-type blades by corresponding angles to reduce the windward area, so the wind power generating set has the characteristics of strong wind resistance, no limitation of wind direction and safe and stable running. The wind power generating set is applied to both the 1kW to 10kW small-sized wind power systems and the megawatt-grade large-scale wind power systems.

Description

technical field [0001] The invention relates to wind power generation equipment, in particular to a vertical axis wind power generation device, which belongs to the technical field of renewable energy. Background technique [0002] At present, the composition of world energy consumption is dominated by coal, oil, natural gas and other non-renewable energy sources. The excessive development and utilization of non-renewable energy has not only brought about an energy crisis, but also brought about increasingly serious environmental pollution problems. For example, due to the extensive use of low-quality coal, 70% of my country's land has been affected by acid rain. Acidification of water bodies will change aquatic ecology, and acidification of soil will make soil barren and lead to the degradation of terrestrial ecosystems. With the global warming and energy crisis, all countries are stepping up the development and utilization of wind power to minimize the emission of carbon ...

Problems solved by technology

However, the lift-type vertical axis wind turbine has two major shortcomings that limit its application. One is its low aerodynamic performance, and another "fatal" shortcoming is that it has no "self-starting ability".
