As the nature of stroke size, orientation has great randomness, resulting in fast wind turbine at a slower speed when the issue of the voltage amplitude and frequency are also chaotic. Wind power converter 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, China, been able to independently produce two-megawatt permanent magnet direct-drive generator sets, but with units supporting grid converter is entirely dependent on imports, severely constrained the domestic wind power industry. Since 2000, the Naval University of Engineering Institute of Power Electronic Technology researchers in China Academy of Engineering Ma Weiming, under the leadership of the high-power converter system of control theory analysis, the device-level and circuit-level integration, optimization and other aspects of design and engineering practice to start an in-depth study, has successfully developed 500 kW general purpose inverter, 500 kVA Static main converter power supply system, a high-speed induction wind turbines systems megawatt-level static excitation converter system and a number of science and technology with independent intellectual property rights result, the access to high-power converter design. In 2007, they are self-financing, has a joint Daqo Group Co., Ltd., Hunan Electric Co., Ltd., independently developed high-power permanent-magnet direct-drive wind power converter. After two years of hard research, and finally broke through the key high-power converter technology and design "bottleneck" has successfully developed with independent intellectual property rights 2 megawatt permanent magnet direct-drive wind energy converter. The converter is running high-performance, power density to meet the harsh operating environment, you can type with the corresponding permanent magnet direct drive wind turbine generator directly supporting and providing high-quality standard-frequency power supply that can completely replace the imported permanent-magnet synchronous direct Drive-type wind turbine auxiliary converter system efficiency and voltage harmonics in the system is superior to other indicators of similar foreign products. According to reports, this result is not only to meet the future of direct-drive type wind power generation applications, the demand can also be extended to ships, aircraft and other applications, for new energy, distributed generation technology, localization plays an important role in promoting.
