Problems solved by technology

The P-circle protection algorithm is more researched now, but the P-circle protection algorithm is suitable for the protection of the grid network, and has no advantages for the protection of the chain network. However, the current power communication network is not all grid networks, and There is a network combining the chain network and the grid network, and it is not enough to use the P circle protection algorithm alone

Abstract

The invention relates to a preset protection method for a power communication network. The network topology of the power communication network combined with the chain and the grid is analyzed; such atype of power communication network is jointly protected based on the chain protection algorithm and the P-circle algorithm. The preset protection method for the power communication network comprisesthe steps of network decomposition, basic protection path generation, service flow analysis, and configuration protection path. Firstly, the network topology is input, a clustering coefficient of eachnode is calculated, and the network is decomposed by using the clustering coefficient; then, based on the P-circle algorithm and the chain protection algorithm, a basic protection path is generated;finally, a protection path is configured for the network by analyzing the traffic. The preset protection method for the power communication network in the invention is based on the chain protection algorithm and the P-circle algorithm and is suitable for the preset protection of the power communication network combined with the chain and the grid, thereby improving the network protection efficiency and reducing the network redundancy.

Description

technical field [0001] The invention relates to the field of power communication network survivability and network service flow analysis, and specifically describes a power communication network preset protection method based on joint protection of a chain protection algorithm and a P circle protection algorithm. Background technique [0002] Power grid information technology is an important guarantee for the safe and stable operation of the power grid. Grid information technology is the specification, design and development of systems and tools for the collection, description, processing, protection, transmission, communication, representation, management, organization, storage and remediation of grid information. The power communication network is the carrier of power grid management information and production control data transmission, a major driving force for the development of modern power grid technology, and an important means to ensure the safety, stability and econ...
