wind turbine, using full-power converter control
Zhuzhou Electric Co., Ltd. announced that it has developed proprietary high-speed permanent magnet synchronous 2.5-megawatt wind turbine can reduce consumption of 85% of rare earth materials.
CSR Zhuzhou Electric Co., Ltd. Chinese propaganda minister Zhu Jianfei, the company and CSR Zhuzhou Electric Locomotive Research Institute jointly launched a new 2.5-megawatt high-speed permanent magnet synchronous wind turbine, using full-power converter control, innovative technology, high efficiency , small size, high reliability, low maintenance advantages. New wind turbine with the same traditional direct-drive permanent magnet wind power generator, compared to 85% reduction of rare earth materials consumption.
Reporters from a number of key enterprises understand that wind power generation, manufacturing, direct-drive permanent magnet wind generator without extensive use of rare earth permanent magnet material NdFeB. In recent years, a variety of factors have led to soaring prices of NdFeB, many electric companies do carry a heavy cost pressures, some even into the raw material cost and machine price "upside down" dilemma. Zhu Jianfei that high-speed permanent magnet synchronous wind turbine generator if proven and widely used, to reduce China¡¯s wind power industry is significant dependence of rare earth.
