China’s First Offshore Permanent Magnetic Direct Drive 2.5MW Wind Generator Unit Rolls Off Production Line in Dafeng City of Jiangsu Province
Recently, China’s first 2.5MW power generator unit, which was produced by CSR Zhuzhou Electric Motor Co., Ltd. CSR Motor, successfully rolled off the production line in Dafeng City of Jiangsu Province.
Permanent Magnetic Direct Drive Power Generator is of such strong points as reliable generator unit, simplified structure, and low running noise, thus it is touted as tiptop product in contemporary power generation sector. As early as February 2008, CSR Motor joined hands with the Goldwind Science & Technology to embark on the R & D of offshore wind power generation products. On the basis of existing mature 1.2MW and 1.5MW permanent magnetic synchronous wind generators, they only spent 2 months to complete the research and production of the 2.5MW offshore wind power generator that is characterized by low rotation speed, simple structure, few components, high reliability, and free from maintenance. After that, the power generator was delivered to the Goldwind Science & Technology for general assembly.
CSR Motor is China’s technical leading enterprise in traction motor and transformer, core components of the rail transit equipment. In 2004, the company established strategic partnership with Xinjiang Goldwind Science & Technology Co., Ltd. to incorporate the Motor Research Laboratory of National Wind Power Generation Engineering Technical Research Center”, in which they successively developed and produced 750KW, 800KW, 1.2MW and 1.5MW power generators. By now, CSR Motor has become China’s largest MW-level power generator manufacturer, with annual output hitting 2000units.
It was learned from the principal of CSR Motor that by the middle 10 days of this month, CSR Motor only spent 4 years to achieve four leap-forward growths in the MW-level power generator production, namely, its production capacity respectively hit 50 units, 380 units, 1500 units, and 2000 units. This year, CSR motor will deliver 60 units of power generators to the Goldwind Science & Technology, and it is predicted that the company will deliver 600 units the next year. At the present day, CSR Motor’s products have been applied in several wind farms like Tongliao of Inner Mongolia, Dabancheng of Xinjiang, and Dafeng of Jiangsu.
China has abundant offshore wind energy resources, for instance, the wind energy resources within 10m water depth are about 100 million KW, that within 20m water depth, 300 million KW, and within 30m water depth, about 490 million KW. The value of quantity of offshore wind energy in China is 3 times that of onshore wind energy, thus China has potential prospect in the development of offshore wind energy resources. Needless to say, wind power generation is of zero pollution to environment, and one 2.5MW power generation unit can generate 21.90 million kW/H per year, which can meet 12166 households’ demands for electricity.
