日前,中国西电研制的首台哈郑±800kV直流输电工程用换流变压器一次性通过全部试验,各项指标满足或优于国家标准和技术协议的要求,其技术性能达到了国际领先水平。哈密-郑州±800kV直流输电工程是疆电外送第一条特高压直流输电工程,也是我国第一个风火打捆直流输出工程。工程西起新疆维吾尔自治区哈密地区哈密换流站,东至河南省郑州市郑州换流站,输电距离约2 210km。2012年10月,在国家电网公司哈密-郑州±800kV特
A few days ago, the first Harbin-Zheng ± 800kV HVDC transmission converter project developed by China’s West Power passed all the tests at one go. All the indexes met or exceeded the requirements of national standards and technical agreements, and their technical performance reached the international advanced level. Hami-Zhengzhou ± 800kV DC transmission project is the first UHV DC transmission project delivered by Xinjiang Uygur Autonomous Region. It is also the first direct-current wind turbine project in China. Project west of Hami, Xinjiang Uygur Autonomous Region Hami converter station east of Zhengzhou City, Henan Province, Zhengzhou converter station, transmission distance of about 2 210km. In October 2012, the national grid company Hami-Zhengzhou ± 800kV special
