Abstract

The invention discloses a reliability node clustering method in a power communication network. The reliability node clustering method comprises a predefining stage and a stage of a method for configuring a cluster with maximum reliability. The method for configuring the cluster with maximum reliability comprises the steps of selecting a cluster head; adding a node into the cluster; selecting a backup node as a cluster head node; inspecting and repairing a cluster structure and the like. According to the reliability node clustering method in the power communication network provided by the invention, the reliability of the power communication network can be effectively improved, the service time delay can be guaranteed, and the resource utilization rate and the comprehensive communication capability can be improved simultaneously; furthermore, at the stage of the method for configuring the cluster with maximum reliability, the effective time of a cluster head node and cluster member nodes can be effectively prolonged, and the energy consumed for configuring the nodes in the period of the cluster can be reduced.

Description

technical field [0001] The invention belongs to the technical field of power communication, and in particular relates to a reliability-oriented node clustering method in a power communication network. Background technique [0002] The power communication network is an important part of the power grid. It runs through the six major links of the entire power grid, including generation, transmission, distribution, transformation, use, and dispatch. It is the key to efficient, safe, and reliable operation of the power grid. With the application and development of new technologies and new energy sources in the power grid, a large number of services suitable for such applications have emerged one after another. More and more smart power terminals, sensor devices, and portable terminals are deployed in the power communication network, serving as an Operators and users provide services such as monitoring, control, information collection, and intelligent power consumption. These ser...
