Abstract

The invention discloses a switching station integrated intelligent terminal, which comprises an auxiliary measurement and control board and main control devices, wherein the auxiliary measurement and control board is connected with multiple main control boards via a bus processing module; the bus processing module is connected with a man-machine interface module; the auxiliary measurement and control board is connected with a distribution main station; the main control devices are connected with the switching stations via the man-machine interface module; and ring connection is formed among the multiple main control devices through a bus association relation or a link line association relation among sides of the switching stations. Quick communication is carried out between multiple main control devices and among the main control devices and the auxiliary measurement and control board via photoelectric signals, fault signals are transmitted, and the problems that fault processing and control are in the main station, and long fault isolation time and long power supply recovery time can be solved.

Description

Technical field: [0001] The invention relates to the field of power transmission and transformation, in particular to a comprehensive intelligent terminal for switching stations. Background technique: [0002] With the development of the national economy and the continuous improvement of people's material and cultural living standards, users have higher and higher requirements for power supply reliability. Power outages not only cause inconvenience to people's lives and bring great economic losses, but also have a great negative impact on society. Relevant studies have shown that every kilowatt-hour of power outage will bring an average economic loss of 40 yuan to users, and the economic loss caused by power outages in my country reaches hundreds of billions of yuan every year. Therefore, the power supply reliability of the distribution network needs to be improved urgently, and solving the fault handling problem of the distribution network is the key to improving the power...
