China's first "PM Metro" operation: energy 30%-Metro-IT information
Times electric company posted after the adoption of the review, the first column "permanent magnet subway" Line 1 subway was put into passenger operations in Changsha. This is China's first passenger-carrying operation of qualified independent "PM Metro", opening of urban rail transit in China "permanent magnet time", its integrated energy-saving rate is as high as 30%.
This install Chinese-made permanent magnet traction system of metro train from Changsha Zhuzhou electric locomotive in the rail transportation group, Ltd and CSR times electric company in joint research and development. The beginning of 2015 "PM Metro" overall design plan March 2016 run trains on the line to accept assessment.
According to China Times electric technology experts, compared with common Metro trains, permanent magnet motor traction system trains more efficient and higher power density, integrated energy-saving up to 30%. A case study of Changsha Metro, if using permanent magnet traction system, electricity can save 5.5 million Yuan a year.
For more energy-efficient, more lightweight and lower life-cycle cost advantages of permanent magnet traction system is considered to be the next generation of train traction systems. Earlier, the international giants such as Alstom, Bombardier, production rail traffic magnet train in France, and Japan and other countries successfully commercialized. As the first independent "PM Metro" put into use, the international competitiveness of China's urban rail transit equipment also increased significantly, urban mass transit of the future will bring more economic and social benefits.
中国首列“永磁地铁”投入运营：可节能30% - 地铁 - IT资讯
中车时代电气公司发布消息，在通过评审后，中国首列“永磁地铁”已在长沙地铁1号线正式投入载客运营。这是中国首列具备载客运营资质的自主化“永磁地铁”，开启了中国城市轨道交通的“永磁时代”，其综合节能率高达三成以上。
这列安装了中国国产永磁牵引系统的地铁列车，由长沙市轨道交通集团、中车株洲电力机车有限公司和中车时代电气公司联合研发。2015年初“永磁地铁”总体设计方案出炉，2016年3月列车上线接受运行考核。
据中车时代电气技术专家介绍，与普通地铁列车相比，永磁牵引系统列车的电机更加高效、功率密度更高，综合节能达30%。以长沙地铁为例，如果采用永磁牵引系统，每年可节省550万元电费。
因具有更加高效节能、更加轻量化和更低全寿命周期成本等优点，永磁牵引系统被认为是下一代轨道交通列车牵引系统。此前，阿尔斯通、庞巴迪等国际巨头生产的轨道交通永磁列车已在法国、日本等国成功商业化。随着首列自主化“永磁地铁”投入使用，中国城市轨道交通装备的国际竞争力也显著增强，将给未来城市轨道交通带来良好的经济和社会效益。
