Embodiment 1

[0019] The node type definition of compound linked list:

[0020]

[0021] The value of model is 1, indicating that the key fields and ts values ​​in the context are generated according to the automatic generation rules, and the value of 2 is not automatically generated, and the original value is used.

[0022] End condition structure definition:

[0023]

[0024] Assuming that the first node of the composite link SList is phead, and phead->pnext can traverse the entire SList, and the pnext marked as a certain node at the end is empty.

[0025] Replication is implemented as follows:

[0026] Set the first copied node to be pbeg, and the last node to be pend, clear the condition value of each node when copying, and set the model of each node to 2; set the previous node at the position to be inserted after copying is pin1, and the next node is pin2;

[0027] 1) Set pin1->pnext as pbeg;

[0028] 2) Set pend->pnext to pin2;

[0029] 3) If the operation mode is selected ...

Abstract

The invention relates to a method for generating and editing a GOOSE message sequence. The method is characterized by comprising the following steps: (1) generating the message sequence: storing the message sequence by using a composite link list, wherein each frame of message is a node (pFNode) in the composite link list (SList), and editing the message sequence by means of pFNode replication, and insertion and deletion operations of the composite link list, wherein the pFNode comprises: a context (context) of a message structure, a pointer (pnext) appointing to the next pFNode, a time interval (ts) with the next frame of message and a termination condition (condition). By adoption of the method provided by the invention, the problem relay protection personnel cannot conveniently and efficiently edit the message sequence when performing a communication fault tolerance test on a relay protection device is solved.

Description

technical field [0001] The invention relates to a method for generating and editing GOOSE message sequences. Background technique [0002] The communication process refers to the process of exchanging a series of communication messages between two parties (or multiple parties, such as SV subscription means one send and multiple receive) in order to complete a certain function or purpose. It can be seen that the communication process has four elements, respectively It is the sender and receiver of the communication message, the content of the communication message, and the sending time of the communication message. An important concept in the communication process is context, which means that the order in which various messages appear is strictly regulated and must be strictly followed. [0003] For the GOOSE message test, the sent message sequence is a communication process, and the sender and receiver are associated through the multicast address or APPID (because GOOSE bel...
