China Makes Huge Breakthrough in Wind Power Technology
Chinese developers unveiled the world’s first full-permanent magnetic levitation (Maglev) wind power generator at the Wind Power Asia Exhibition 2006 held June 28 in Beijing, according to Xinhua News.
Regarded as a key breakthrough in the evolution of global wind power technology-and a notable advance in independent intellectual property rights in China — the generator was jointly developed by Guangzhou Energy Research Institute under China’s Academy of Sciences and by Guangzhou Zhongke Hengyuan Energy Science & Technology Co., Ltd. The Maglev generator is expected to boost wind energy generating capacity by as much as 20 percent over traditional wind turbines. This would effectively cut the operational expenses of wind farms by up to half, keeping the overall cost of wind power under 0.4 yuan ($US 5 cents), according to Guokun Li, the chief scientific developer of the new technology. Further, the Maglev is able to utilize winds with starting speeds as low as 1.5 meters per second (m/s), and cut-in speeds of 3 m/s, the chief of Zhongke Energy was quoted as saying at the exhibition. When compared with the operational hours of existing wind turbines, the new technology will add an additional 1,000 hours of operation annually to wind power plants in areas with an average wind speed of 3 m/s.
Research from Worcester Polytechnic Institute (Massachusetts)
This project focuses on the utilization of wind energy as a renewable source. In the United States alone, wind capacity has grown about 45% to 16.7GW and it continues to grow with the facilitation of new wind projects [2.2]. The aim of this major qualifying project is to design and implement a magnetically levitated vertical axis wind turbine system that has the ability to operate in both high and low wind speed conditions. Our choice for this model is to showcase its efficiency in varying wind conditions as compared to the traditional horizontal axis wind turbine and contribute to its steady growing popularity for the purpose of mass utilization in the near future as a reliable source of power generation. Unlike the traditional horizontal axis wind turbine, this design is levitated via maglev (magnetic levitation) vertically on a rotor shaft. This maglev technology, which will be looked at in great detail, serves as an efficient replacement for ball bearings used on the conventional wind turbine and is usually implemented with permanent magnets. This levitation will be used between the rotating shaft of the turbine blades and the base of the whole wind turbine system. The conceptual design also entails the usage of spiral shaped blades and with continuing effective research into the functioning of sails in varying wind speeds and other factors, an efficient shape and size will be determined for a suitable turbine blade for the project.
