Abstract

The invention relates to a multi-attribute decision-making based power backbone transmission network route planning method. The multi-attribute decision-making based power backbone transmission network route planning method comprises the steps of determining a network topology and obtaining load information of each link; calculating node importance of backbone nodes according to the condition of the network topology and an agglomeration degree of nodes; assessing a risk degree of the backbone nodes based on the network topology and importance of services; and performing route planning based on multi-attribute decision-making of the node importance and the risk degree. During path selection, the routing method of the invention not only gives consideration to the importance of the services in the network and the service risk, but also gives consideration to the values such as the topological environment of the communication network and the agglomeration degree of the nodes. According to the provided multi-attribute decision-making based route optimization method, communication network risk can be balanced efficiently, reliability of the power backbone transmission network is increased, network operation is adjusted efficiently, and the power system backbone transmission network is accordingly ensured to run more safely and more reliably. The multi-attribute decision-making based power backbone transmission network route planning method can be widely applied to the power backbone communication network planning field.

Description
