Relay protection communication system based on 5G communication and communication method

Abstract

The invention relates to a relay protection communication system based on 5G communication and a communication method. The relay protection communication system is a composite network communication architecture formed by relay protection devices and wireless terminals in a plurality of relay protection communication nodes so as to transmit relay protection data. Under a point-to-point composite network communication architecture formed by a relay protection communication system, each node automatically detects a connection node according to a configuration node characteristic, finds a node which needs to be communicated, and establishes communication of the whole composite network communication architecture. Because the 5G wireless communication speed is high and the actual physical link does not need to be produced and maintained, through the technical scheme of the invention, the communication capability between the digital substation relay protection devices is improved, and the debugging and maintenance pressure is reduced.

Description

technical field [0001] The present invention relates to the field of power system relay protection, in particular to a relay protection communication system and communication method based on 5G communication. Background technique [0002] With the widespread application of digital substations, physical channels such as optical fibers are used for data communication between relay protection devices, which has brought great pressure to engineering construction and commissioning. For communication devices such as boxes and switches, each node has a clear label, but because there are many fibers connected to the splice box and the switch, it will be very difficult to debug and maintain when the label falls off or the meaning of the label is unclear. [0003] With the gradual development and maturity of 5G communication technology, the application of a composite network communication architecture of relay protection devices based on 5G communication has emerged. 5G communication ...
