Discussion about the Information Management and the Intellectualization of Unattended Substation

摘要

Carry on unattended substation at the voltage of 220kV and the following is a technological innovation which having the profound influence to the current power supply system, is also the most important technology safeguard measure of the downsizing for efficiency in the power supply system. Along with the development of modern communication technology, computer technology, network technology, automatic control technology, image technology, monitoring technology and weak electricity integration technology, we had already realized the image and the sound signal's digitization, the audio and video signal's processing and the long-distance transmission. To the substation, besides the remote measurement, the remote signaling, the remote control, and the remote regulating functions which have already realized, the remote monitoring has also increased which called "five remote". The "five remote" caused unattended substation become the reality and give a higher request to the information management and the intellectualization simultaneously. According 10 many years unattended substation's operational guidance experience, I proposed my ideas about the information management and the intellectualization of unattended substation, 1 hope that it is helpful to the promotion of the unattended substation.
