The tests, undertaken at XEMC’s generator test facility in Xiangtan in China’s Hunan province, verified critical design parameters of performance and safety as well as overall effectiveness of the new wind turbine.
Chinese wind energy manufacturer Xiangtan Electric Manufacturing Corporation Ltd (XEMC) has recently unveiled the world’s first 5 MW permanent magnet direct-drive offshore-specific wind turbine. The achievement was marked by a 21st October ceremony in Xiangtan which was attended by leading officials representing regional and national government including the Vice Minister of the Ministry of Science and Technology Cao Jianlin.
The announcement follows successful completion of full load, back to back, testing of the turbine in which Converteam participated with its class leading Medium Voltage “MV7000” power converter. The tests, undertaken at XEMC’s generator test facility in Xiangtan in China’s Hunan province, verified critical design parameters of performance and safety as well as overall effectiveness of the new wind turbine.
The power converter is a critical component of any wind turbine as it allows optimisation of the generator’s power output and ensures continuous operation even in low wind conditions and optimal grid stability. Converteam’s medium voltage MV7000 range of power converters recognises the trend towards the development of ever more powerful offshore wind turbines and the consequent demands for equipment of the highest efficiency and reliability.
Mr. Zhao Wenhong, General Manager of XEMC Wind spoke warmly of the co-operative working with Converteam: “It is clear that the future of offshore wind lies in the development of wind turbines of ever greater power output. Converteam has shown itself to be a reliable and co-operative partner which has technologically superior products as well as the engineering skills that are essential as we bring our most innovative new products to the global market.”
Alain Guy, Vice President Global Wind at Converteam expressed his satisfaction with the successful tests: “We are very proud of this new reference for a medium voltage converter in wind. Medium Voltage is gaining more and more interest from the offshore wind energy industry as the power of turbines increases, due to the demand of the offshore market; Medium Voltage enables us to increase efficiency of the whole system and can be a good solution for high power wind turbines.”
Converteam, a world leader in wind converters with more than 20,000 MW installed worldwide, was the first company to deliver a medium voltage converter in wind in 2004, leveraging strong expertise from other demanding industrial sectors (such as metals, marine, or oil and gas), where we have delivered more than 4,000MW of MV7000 so far.
XEMC plans to initially install two of this new class of turbines by the end of 2010, one in China and the other in Europe.
Xiangtan Electric Manufacturing Corporation Ltd (XEMC). was founded in 1936. With development of seven decades nearly, it has been the domestic manufacture and R&D base for the significant technology and equipment of China, and a pointed defense equipment manufacturing base.
XEMC Windpower Co., Ltd., covers an area of 200,000 square metres, with paid –in capital of RMB 310 million Yuan, mainly engages in design, manufacture, sale and service of wind turbines, enjoys a capacity to deliver 1000 sets of MW wind turbines a year. The company possesses up-to-date technology of design and manufacture of direct drive wind turbine, first-class manufacturing equipment and excellent management team; it is one of the leading corporations in MW class wind turbines manufacturing industry in China.
XEMC Windpower Co., Ltd is the pioneer in large-sized wind turbines manufacturing industry in China. As early as in the mid of 1990’s, XEMC undertook and finished R& D of 300kW, 600kW double-winding and double-speed asynchronous generator for wind turbine application, which was listed in the 9th Five-Year-Plan State Level Key Research Program sponsored by the Ministry of Science and Technology and the National Committee of Planning, and successfully developed the first 300kW and 600kW asynchronous generator in China which won technology advancement award of machinery industry. Entrusted by the National Standard Committee of Wind Turbine, XEMC compiled the national standard of General Technical Specifications and Test Method for Grid Type Asynchronous Generators, which had been promulgated. Hunan XEMC Windpower Co., Ltd has completed the self-development & research of large-sized wind turbine, which greatly makes influence to the wind energy industry and takes the leading position in the same trade.
XEMC Windpower Co., Ltd is the key industrialization base of MW wind turbine designated by Central Government. Taking advantage of 70 years manufacturing experience of complete set of large electromechanically equipment of XEMC and consolidating comprehensive power of producing wind turbine components, such as generator, control equipment, large casting and forging, and structure parts, the company displays its unique performance in large-sized wind turbine equipment manufacturing industry and is highly supported by the state. In Sept,2005, the State Committee of Development and Reform (m2005n1899 ) issued approval for the mass production of MW wind turbine by XEMC.
XEMC Windpower Co., Ltd enjoys the ability of developing first-class products and self-innovation. Provided with a National Centre authorized by the state, the company owns a number of first-class technical professionals and experts. The company has undertaken four tasks which are listed in 863 programs of 11th Five-Year-Plan and the National Science and Technology Support Project. The four tasks are as follows: firstly, design and manufacturing technology of 2MW direct drive wind turbine and its key components; Secondly, R & D of 2.5 MW variable speed and constant frequency Wind Turbines; Thirdly, R & D and industrialization of permanent magnet generator of 1.5 MW direct drive wind turbine; Fourthly, R & D and industrialization of 1.5 MW double-fed generator of wind turbine.
Products of XEMC Windpower Co., Ltd has up to date technology and huge bright prospect. Compared with traditional wind turbine, the direct drive wind turbine manufactured by the company owns distinct advantages of high efficiency, gearless, reliable system, easy maintenance, low noises and good quality of grid connection. This type of product represents the developing trend of international wind turbine technology, and it is popularly installed in Netherlands, Finland, Germany, Japan, and Taiwan as well as Northern part and coastal area of China, which enjoy high evaluation from customers.
