Efficiency of permanent magnet wind power generation

Rated power: 5MW-7MW Rated voltage: 690V/3300V Rated frequency: 60.6Hz Efficiency: >=97.5% Insulation level: Class H Vibration speed: 2.8mm /s By selecting representative offshore wind turbines with high-speed permanent magnet wind turbines, combined with the development and test results of typical prototypes, improve the design method of high-speed permanent magnet wind turbines and realize the spectrum design high-speed permanent magnet wind turbines. The technology development unit uses independently developed marine generators with a power range of 300 kW to 5.3 MW to master high-power engine development technology. At the same time, we develop 1200 kW and 4.5 MW permanent magnet propulsion motors and master the development technology of permanent magnet propulsion motors. We have developedmany types of motor products with independent intellectual property rights, covering medium voltage and high power marine generators, offshore platform generators, dual-fed asynchronous wind turbine series, synchronous wind turbine series, variable frequency motors for oil fields. , etc., with rich R&D, design, process manufacturing and test verification capabilities of powerful motors. Promote the existing high-power development technology of military engines and permanent magnet motor manufacturing technology to high-speed permanent magnet wind turbines for offshore wind turbines, and master the key core design technologies of magnet wind turbines high-speed permanent and high-power permanent magnet generator manufacturing technology. Develop a series of high-speed permanent magnet wind turbinesse for offshore wind turbines and form a series of high-speed permanent magnet wind turbine products with independent intellectual property rights. performance, fully meeting the requirements of offshore wind turbines.
