In the development of global power information technology, China was once in an absolute leading position. In the mid-1960s, People's Daily reported that Jingxi Gaojing Power Station successfully developed and installed a fully automatic digital closed-loop power generation and distribution management system (so-called DDC, digital direct control), which was the leading technology in the world at that time. At the same time, Hitachi's power automation control system can only achieve open-loop management, that is, the computer system can only monitor power generation, transmission and distribution, and cannot participate in control.

However, as a power generation enterprise, Takai's leading scientific research achievements have been shelved because they can't be transformed into products, and only as an experimental task, they have not been further improved and popularized. On the contrary, Hitachi, which was one step behind in that year, constantly developed new technologies and put them on the market in the form of products in the later period, so it gained an absolute advantage in the later power information technology market.
