Application of microcomputer-based integrated automation systems for power transformation and distribution

Please discuss the application of microcomputer-based integrated automation systems for power transformation and distribution
Power distribution monitoring systems have been implemented for both high and medium voltage in large enterprises. The main purpose is to achieve unattended operation of the power distribution room, thereby reducing the operating costs of the enterprise. There are many companies in China that specialize in power automation, such as NARI and NARI Group
The question raised by the poster is very good. The application of microcomputer-based integrated automation systems for power transformation and distribution has made it possible to have substations that do not require on-site personnel, and it also improves the functionality of remote operation and control systems. The protection systems have been upgraded from relay-based protection to microcomputer-based protection, which reduces the number of intermediate control components and thereby significantly lowers the failure rate in substations.
Domestic leading enterprises: NARI, NARI, XJ, Sifang.
Substation automation systems have evolved from centralized substation automation systems (based on RTU + four remote functions, IED + protection management unit) to hierarchical distributed substation automation systems. Currently, hierarchical distributed substation automation systems have been widely applied. Furthermore, thanks to the development of intelligent circuit breakers, the use of unconventional current transformers, and the promotion of IEC61850, fully digital substations have been introduced. In 2006, China’s first fully digital substation was established.
This is the future development direction of substations.
