Problems solved by technology

At present, in scenarios involving power grid line protection, a single network modeling method is usually used to evaluate and analyze the nodes in the power grid, but it ignores the topological structure and service characteristics of the power network and power communication network in the power grid. Coupling relationship
There are similarities between the distribution topology of the power optical fiber communication network and the power line. However, the evaluation of the power grid in related technologies does not consider the node characteristics of the power fiber optic communication network and the power line network architecture in the power grid, and does not consider the topological relationship between the power network and the power communication network. Included in the evaluation, so the overall evaluation result of the power grid is not scientific enough
[0003] For the above problems, no effective solution has been proposed
