Problems solved by technology

[0004] The transmission of power grid lightning location information generally adopts dedicated line and private network communication. Once the dedicated line and private network fails or a certain transmission line is interrupted for some reason, the communication will be interrupted and the normal operation of the lightning positioning system will be affected.
Therefore, the transmission reliability from the existing lightning detection point to the lightning location analysis center cannot be effectively guaranteed

Embodiment Construction

[0023] like figure 1 As shown, a method for transmitting lightning location information in a power grid is: the pulse burst signal generated by the lightning detection point is struck by lightning at the same time through the power dedicated line network that uses time division multiplexing to transmit real-time data and the IP interconnection protocol-based enterprise local area network dual communication The channel is sent to the lightning location analysis center. The lightning location analysis center receives the burst signal from the lightning detection point and performs data processing.

[0024] Power grid lightning location information transmission system, including power dedicated line network equipment and IP network equipment;

[0025] Power dedicated line network equipment, including a central modem suitable for power communication systems and capable of communicating with each lightning detection point, the central modem includes: a plurality of receivers and t...

Abstract

The invention provides a method and a system for transmitting electric network lightning positioning information, in particular a method and a system for transmitting the electric network lightning positioning information through a dual communication channel of an electric private network which adopts time-division multiplexing to transmit real-time data and an enterprise local area network which is based on IP interconnection protocol. The method and the system improve the reliability of transmitting lightning control points to a lightning positioning analysis center, so as to increase the operational stability of a lightning positioning monitoring system.

Description

technical field [0001] The invention relates to a method and a system for transmitting power grid lightning positioning information, in particular to a method and system for transmitting power grid lightning positioning information through dual communication channels. Background technique [0002] The damage caused by lightning damage to the power system is huge. Lightning strikes will cause tripping accidents and affect the reliability of power supply. If power plants and substations are built in areas where lightning damage occurs frequently, it is easy to cause large-scale power outages and affect the power supply of various industries. Safe Production. After the lightning strikes the transmission line, it is not easy to locate the fault point accurately and quickly, and the lightning protection characteristics of the line cannot be quantitatively evaluated. Therefore, it brings inconvenience and trouble to dealing with defects. [0003] The lightning location monitoring...
