Jiangsu Daqo Group 2 megawatt permanent magnet direct-drive wind energy converter has recently passed appraisal departments. The achievement of China's high-power direct-drive wind energy converter technology, localization and industrialization has provided technical support to fill the domestic blank, reached the international advanced level.

    Wind generator converter is indispensable for wind turbine energy conversion device is a wind turbine, one of the core components. Its main role is to wind generator voltage frequency, amplitude of the electric energy is converted to a floating variable frequency, amplitude stability, and meet the requirements of power grid. At present, Chinese enterprises, been able to independently produce two megawatts of permanent-magnet direct-drive generator sets, but with units supporting grid converter is entirely dependent on imports, severely restricted the development of domestic wind power industry.

    In 2007, Daqo Group and the Naval Engineering Technical University, Hunan Electric Co., Ltd. joint, self-developed high-power permanent-magnet direct-drive wind power converter. After a difficult research, breaking through the key high-power converter technology and design of the "bottleneck" has successfully developed with independent intellectual property rights 2 megawatt permanent magnet direct-drive wind energy converter.

    The product is running high-performance, power density to meet the harsh operating environment, with a corresponding permanent magnet direct-drive type wind turbine directly supporting, but also to provide high-quality standard-frequency power supply, completely replace the imported direct-drive type permanent magnet synchronous wind generators  auxiliary inverter system, the performance is superior to similar foreign products.

    According to reports, the product is not only the future of direct-drive type to meet the application requirements of wind power can also be extended to ships, aviation and other applications, for advancing the development of new energy, distributed power generation technology has a positive role in localization.
