Title:

METHOD FOR AVOIDING DATA MESSAGE COLLISION IN COMMUNICATION NETWORK WITHIN SUBSTATION

Document Type and Number:

WIPO Patent Application WO/2018/049584

Kind Code:

A1

Abstract:

The present invention relates to a method for avoiding a data message collision in a communication network within a substation, characterized by comprising the following: 1) distinguishing a message data source for data service sources of GOOSE, SV, MMS and IEEE1588; 2) identifying a data message type according to the result of distinguishing the massage data source; 3) enabling a data message priority mechanism to define a substation service according to the priorities of different data message types; 4) defining a data message multicast management protocol of the substation; 5) defining a corresponding data message CSMA policy for different data message types; and 6) defining a corresponding data message collision avoidance algorithm for different data message types. The invention can avoid the communication network in the substation becoming congested, reduce the packet loss rate and delay of the communication service, improve the performance of the communication network within the substation, and improve the real-time performance, stability and reliability of the operation of the substation.
