Embodiment Construction

[0068] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific illustrations.

[0069] like figure 1 As shown, a method for measuring the reliability of transmission time based on a multi-state network is characterized in that: comprising the following steps,

[0070] Step 1. Establish the state model of network nodes: the state model of network nodes for network reliability research only includes two states: work or failure. However, in the actual network system, there will be two or more states. During the operation of the network, the status of each component is affected by factors such as hardware failure, software error, and congestion;

[0071] Let the set of nodes of the multi-state network be . for any node v i , with S ij Indicates the node state, the number of states is h i , that is, j=1,…,h i ;

[0072] S...

Description

[0001] Technical field: [0002] The invention relates to the technical field of power communication transmission network reliability detection, in particular to a method for measuring transmission time reliability based on a multi-state network. [0003] Background technique: [0004] With the rapid development of smart grids, the information interaction between power systems is becoming more and more frequent, and the power communication transmission network [2] will carry more and more services such as control and automation. These services have high requirements on the real-time performance of power grid operation data, and it is necessary to accurately grasp the change law of transmission time and implement effective control, so that the network transmission time becomes an important indicator for examining the reliability of the transmission network. The change law of power system network transmission time needs to be analyzed from a large number of test results. However,...
