证券时报记者 张一帆 "衡长株潭特高压输变电装备产业集群"为什么能成功？对原创性、引领性创新的不懈追求，是这个"集群"中所有企 业共同的"精神基因"。 在这样的日夜耕耘中，衡长株潭特高压输变电装备产业集群以及整个中国特高压产业创造了了不起的成就，为我 国新型能源体系建设作出巨大贡献。 为什么要做原创性研发？"因为在特高压领域，海外也没有形成成熟的技术和设备，我们就是拿着钱也没地方买， 没地方学。" 为什么要做引领性研发？"因为从交流特高压到直流特高压，电流从5000A到8000A，从常规直流到柔性直流，从 低海拔到高海拔，中国的实际应用场景确确实实需要这些前沿的技术储备。" 说到底，目前世界上有且只有中国成功建设了交、直流特高压电网并投入商业运行，而"衡长株潭特高压输变电装 备产业集群"整体领跑世界的技术水平，也是和中国的特高压工程应用与实践同步发展的。 然而，从创新到应用的转化，并非只是财报上看到的"集群企业平均研发投入强度约5%"。这一过程根植于我国超 大规模的市场空间，受益于我国过去20年里建立的工程师红利，更是源于研发人员们日日夜夜直面问题、拆解问 题、解决问题积累而成的破茧成蝶。 从世界一流的技术创 ...
