在全球电力信息技术的发展中,中国曾经一度处于绝对领先的地位。20世纪60年代中期,人民日报发布了一条消息,北京西部的高井电站成功研制并安装了全自动数字闭环发、配电管理系统(即所谓的DDC,DigitalDirect Control)这在当时是一项全球领先的技术。而日立公司同期推出的电力自动化控制系统只能实现开环管理,也就是计算机系统只能对发、输、配电进行监控,而不能参加控制。然而,高井作为一家发电企业,由于无法将科研成果变成产品,而仅仅将其当做了一项实验任务,导致这项领先的科研成果被束之高阁,没能得到继续的完善和推广。相反,当年滞后一步的日立公司,在后期不断开发新的技术并将这些新技术以产品的形式推向市场,因此在后来的电力信息技
In the development of global power information technology, China once was in the absolute leading position. In the mid-1960s, the People’s Daily published a piece of news that Gaojing Power Station in western Beijing successfully developed and installed a fully automated digital closed loop power distribution management system (DDC, DigitalDirect Control) which was a global leader Technology. The same time, Hitachi launched the power automation control system can only open-loop management, that is, the computer system can only send, lose, power distribution to monitor, but can not participate in the control. However, Takai, as a power generation company, has failed to turn scientific research into products and merely treated it as an experimental task, resulting in the leading scientific research being put on the shelf and failed to be further improved and promoted. On the contrary, Hitachi, one step behind, continued to develop new technologies later and bring these new technologies to market as products. Therefore, in the later period of Power Information Technology
