摘　　要：东京电力公司(Tokyo Electric Power Company,TEPCO)在20世纪90年代建成了1000kV南北输电线路和1000kV东西输电线路。文中介绍了日本选择特高压输电技术的经过和TEPCO采用特高压输电的必要性,指出了选择特高压交流最高运行电压时应考虑的因素;还对交流输电方式和直流输电方式进行了比较,分析了直流输电方式存在的问题,说明了TEPCO在特高压输电中采用交流输电方式的原因。对中国发展特高压输电有一定的借鉴意义。Tokyo Electric Power Company (TEPCO) has completed the North-South 1000kV transmission line and the East-West 1000kV transmission line in 1990’s. The Ultra High Voltage (UHV) transmission technology used by TEPCO will be presented in six parts and this paper is the second part. Here, the authors present the development process of the UHV transmission technology in Japan and the necessity of applying UHV transmission in TEPCO, point out the factors to be considered when the highest AC operating voltage of UHV is determined. It also concerns to discuss comparison between AC and DC transmission, analyzes problems in DC transmission, and explains reasons why the AC transmission is selected by TEPCO. Above-mentioned contents may be available for reference to develop the UHV transmission in China.
