尽管起步较晚,但近年来我国直流输电已进入大规模发展阶段。在中国电科院成功研制出特高压直流领域核心技术——换流阀之前,我国直流技术和设备长期依赖进口,国产化进程步履维艰,而核心设备的定价权一直握在他人之手。当世界首个±800千伏/4750安特高压直流换流阀在国家电网公司电力系统电力电子实验室通过型式试验时,一种新的竞争格局和市场划分从此展开,同时铺展的还有我国未来壮丽的特高压直流输电画卷。
Despite the late start, DC power transmission in China has entered a stage of large-scale development in recent years. Before the Chinese Academy of Electric Power Research successfully developed the core technology of UHVDC - converter valve, China’s long-term dependence on imported DC technology and equipment, the localization process struggling, while the core equipment pricing power has been in the hands of others. When the world’s first ± 800 kV / 4750 Ampere HVDC converter valve passed the type test at the Power Grid Power Electronics Laboratory of State Grid Corporation of China, a new pattern of competition and market division began. At the same time, The future magnificent UHVDC transmission picture.
