Embodiment 1

[0044] Such as figure 1 Shown, the present invention a kind of power communication network fault identification method, this method comprises:

[0045]S1: According to the communication network nodes and communication network topology, identify the key node set in the entire power communication network; according to the key node set, use inter-node correlation to divide the entire power communication network to form multiple communication area sub-sets Network; Step S1 includes the following sub-steps:

[0046] S11: According to the communication network nodes and communication network topology, the entire power communication network can be represented by an undirected graph G=(V, E), where V represents a communication device node, and E represents the connection relationship between communication devices;

[0047] S12: The identification of key nodes can be understood as that after the key nodes are removed, the node connectivity in the entire communication network is the sm...

Embodiment 2

[0069] Such as figure 2 As shown, the difference between this embodiment and Embodiment 1 is that this embodiment provides a power communication network fault identification device, which supports the power communication network fault identification method described in Embodiment 1, and the device includes:

[0070] The acquisition unit is used to acquire the network communication status of the power equipment in the power system, and aggregate the network communication status of each power equipment according to the cycle dimension;

[0071] The communication area subnet construction unit is used to identify key node sets in the entire electric power communication network according to the communication network nodes and communication network topology; according to the key node set, the entire electric power communication network is divided by inter-node correlation , forming multiple communication area subnets;

[0072] The mapping relationship building unit between the pow...

Abstract

The invention discloses an electric power communication network fault identification method, device and equipment and a storage medium, and the method comprises the steps: S1, recognizing a key node set in a whole electric power communication network, dividing the whole electric power communication network through the correlation between nodes, and forming a plurality of communication region subnets; s2, according to network equipment connected with the power equipment, finding out areas divided by the power equipment corresponding to the communication area subnet, and establishing a mapping relation between the power equipment area and the communication subnet area; s3, finding out faulty power equipment, finding out a power equipment region set containing most faulty equipment according to the faulty power equipment, finding out a mapping relation between power equipment regions and communication subnet regions, and finding out a communication subnet region set of all possible faults; and S4, performing communication equipment fault identification on each communication subnet area with possible faults by using the fault correlation analysis two-layer model. According to the invention, the accuracy of communication network fault identification is improved by fusing power equipment fault information.

Description

technical field [0001] The present invention relates to the technical field of network fault identification, in particular to a power communication network fault identification method, device, equipment and storage medium. Background technique [0002] As the "highway" of power grid information communication, the optical transmission network mainly undertakes the information carrying of various businesses such as power grid production and operation, power dispatching and customer service. With the rapid development of energy Internet, smart grid and power grid informatization, the business volume carried by the power communication network is increasing, and the business types are more abundant, and the service quality requirements are more diversified. Therefore, these changes have great impact on optical transmission network planning. put forward higher requirements. [0003] At present, most of the fault identification methods for power system communication networks are b...
