Smart grid satellite network transmission system

Abstract

The invention discloses a smart grid satellite network transmission system. The smart grid satellite network transmission system comprises a substation data acquisition system, a communication transmission system and a monitoring center system. The data acquisition system is arranged on a high-voltage switch cabinet of a substation. The communication transmission system is located in the China National Space Administration. The monitoring center system is located in a managing user of the high-voltage switch cabinet. The data acquisition system comprises a network node controller, a wide range measuring system and monitoring software. The monitoring software comprises a write-in control component, an operational control component and a node network component. The monitoring software runs in high-voltage switch cabinet nodes of substations. The communication transmission system comprises a Big Dipper satellite, a China National Space Administration satellite communication IISP platform and an application data center. According to the smart grid satellite network transmission system, the monitoring access points can be flexibly updated, the user can upload updated software at any time and at any places in the area covered with the satellite through a remote satellite star network, the working efficiency is improved, and the maintaining cost is reduced.

Description

technical field [0001] The invention relates to an intelligent switch cabinet management method, in particular to an intelligent grid satellite network transmission system. Background technique [0002] With the continuous establishment of ultra-high voltage and ultra-high voltage transmission lines in my country, the transmission network is developing in the direction of comprehensive coverage. my country has a vast territory and diverse geographical environments. The extensive coverage of the transmission network will lead to a harsh environment for line operation, making it difficult to ensure the stability and safety of power supply. Once a line failure occurs, it will bring huge losses to people's normal production and life. Therefore, how to ensure the safe operation of transmission lines has become an urgent problem to be solved by the power sector, and with the continuous growth of transmission lines, the traditional manual line inspection method has become less and ...

my country has a vast territory and diverse geographical environments. The extensive coverage of the transmission network will lead to a harsh environment for line operation, making it difficult to ensure the stability and safety of power supply. Once a line failure occurs, it will bring huge losses to people's normal production and life.

Therefore, how to ensure the safe operation of transmission lines has become an urgent problem to be solved by the power sector, and with the continuous growth of transmission lines, the traditional manual line inspection method has become less and less suitable for transmission line safety and power supply reliability requirements.

[0003] High-voltage switchgears are widely distributed and difficult to maintain. Currently, monitoring software is generally used to realize intelligent management of them. As time goes by, some monitoring parameters and physical quantities of high-voltage switchgears need to be adjusted, and the software needs to be updated regularly. It meets the needs of dynamic management, but because the manual adjustment method is mainly used at present, the maintenance cost is relatively high
