"Vertical shaft wind energy machine with controllable output power" won the national invention patent

"Vertical axis wind energy turbine with controllable output power" has recently obtained the invention patent of the State Intellectual Property Office, and has now entered the stage of international patent application, and is preparing for the construction of a demonstration project
.

The invention patent was successfully applied for by Qin Minghui in October 2012 on the basis of his research results "floating ringless vertical blade wind energy turbine" obtained the utility patent certification of the State Intellectual Property Office
.

According to reports, the "controllable output power vertical shaft wind energy turbine" patent technology demonstration project is currently under active preparation, planning to invest 28 million yuan, the construction of 1000-3000 kilowatt single wind turbine, relying on the existing Inner Mongolia wind farm for technical transformation project implementation, the technical team gathered talents in physics, automatic control, electrical engineering, meteorology and design construction and other fields
.

Its invention principle puts forward innovative ideas and technical principles
in view of the difficulties of existing wind power technology.
Its large-scale wind turbines improve the energy conversion efficiency, and can continuously collect wind energy in different directions at altitudes of hundreds to thousands of meters according to different wind farm characteristics, continuously emit tens of thousands to millions of kilowatts of high-quality electric energy, and overcome the problems of
small concentrated power, low efficiency, and unstable output of existing wind power generation.
In particular, the innovation of "being able to directly go to the national power main grid" to provide high-quality electric energy has attracted the attention
of experts.

According to reports, traditional wind power conversion of high-quality alternating current, need to experience ultra-high power AC conversion and battery energy storage technology, such as direct Internet access, there are technical difficulties, high investment costs, poor power quality, the main network is unwilling to receive and environmental pressure and other problems
.

Lin Limin, deputy chief engineer and director of the new energy project department of East China Electric Power Design Institute of China Power Engineering Consulting Group, believes that the wind turbine cleverly uses the same section of annular floating structure design, breaking through the technical limitations of conventional wind turbines, and is completely different
from the current vertical axis fans in concept, form and scale.
If the technology is successfully promoted, the proportion of wind power generation is expected to account for more than 30% of China's electricity supply, promoting the development of
wind power in China and even the world.
