Embodiment 1

[0063] A power communication backbone network fault recovery method based on artificial intelligence and state awareness, comprising steps:

[0064] Step 1. Obtain the number of nodes in the power communication backbone network at the current moment t that the actual unsaturated nodes are turned into saturated nodes;

[0065] The occupancy degree of node cache is a direct indicator reflecting the state of network communication. However, for the power communication backbone network, a single node status is not enough to reflect the congestion information of all surrounding nodes. If only a certain link is blocked, reasonable forwarding modification can effectively relieve the blocking. Nodes in the network can be divided into saturated nodes and unsaturated nodes according to their cache occupancy status. While judging its own state, the node can also judge the corresponding blocking state according to the return information of other nodes within the communication range. Ide...

Embodiment 2

[0096] A power communication backbone network fault recovery device based on artificial intelligence and state perception, comprising:

[0097] The actual flipped node acquisition module is used to obtain the number of nodes that are flipped from actual unsaturated nodes to saturated nodes in the power communication backbone network at the current moment;

[0098] The node flip prediction module at the next moment is used to correct and predict the number of nodes that are actually unsaturated nodes flipped to saturated nodes by weighting parameters to obtain the number of nodes that are flipped from unsaturated nodes to saturated nodes at the next moment;

[0099] The failure recovery module takes the number of unsaturated nodes turned into saturated nodes at the next moment as the input of the reinforcement learning algorithm. When a link e fails, the reinforcement learning algorithm proposes a new network topology as a recovery strategy, and establishes A new and more effec...

Abstract

The invention discloses a state-aware power communication backbone network fault recovery method and device, which can obtain the number of nodes whose actual unsaturated nodes are turned into saturated nodes in the power communication backbone network at the current moment; according to the number of nodes whose actual unsaturated nodes are turned into saturated nodes The quantity predicts the number of nodes that will turn unsaturated nodes into saturated nodes at the next moment; the number of nodes that will turn unsaturated nodes into saturated nodes at the next moment is used as the input of the reinforcement learning algorithm. When a link e fails, the reinforcement learning algorithm proposes a new The network topology is used as a recovery strategy, and a new and more effective recovery strategy is established according to the feedback obtained, and fault recovery is carried out according to the final recovery strategy. The present invention shows better performance in the fault recovery problem of the power communication backbone network.

Description

technical field [0001] The present invention relates to the technical fields of smart grid and network communication, in particular to a state-aware-based power communication backbone network fault recovery method and device. Background technique [0002] The modern power grid relies on the corresponding communication backbone network, and ensures the safe operation and authority control of the power grid through the communication network. As an important infrastructure, the communication backbone network has different bandwidth, delay and reliability characteristics compared with the general communication network, and its corresponding fault diagnosis, location and recovery issues are also research hotspots. The mainstream method alleviates the channel congestion problem by establishing a fault model of the communication network and buffer capacity, a typical fault detection and recovery method based on distributed deployment (DM-FDR), and a fault detection and recovery met...
