Method and device for establishing power communication network model

Abstract

The invention provides a method and a device for establishing a power communication network model, wherein the method and the device relate to the technical field of a power communication system. The method comprises the steps of acquiring data of a network model structure and service distribution condition of the to-be-processed power communication network; determining a link capacity matrix and a service connection matrix, and determining a network service flow matrix according to the link capacity matrix and the service connection matrix; determining a service flow parameter of each power communication network node in each service type according to the link capacity matrix, the service connection matrix and the network service flow matrix; determining the determined value of importance of each power communication network node according to the service importance of each service type and the each service flow parameter; and correspondingly arranging each determined value of importance and each power communication network node in the network model structure of the to-be-processed power communication network, thereby forming the power communication network model in which each power communication network node has the determined value of importance.

Description

technical field [0001] The invention relates to the technical field of power communication systems, in particular to a method and device for establishing a model of a power communication network. Background technique [0002] At present, the power communication network is an important support network for the power system to ensure the safe operation of the power system, and its reliability is closely related to the reliability of the power system. Due to the continuous expansion of the scale of the power grid, the grid structure of the power communication network is becoming more and more complex, the business volume carried is also increasing, and the security risks and control difficulties are increasing. A reasonable reliability evaluation plan is very necessary for the safe and stable operation of the communication network. [0003] As the private communication network of the power system, the power communication network carries a variety of services, and the service tra...
