Embodiment Construction

[0018] The method for evaluating the reliability of the power communication network provided by the present invention performs quantitative calculation and analysis by combining the path tracing algorithm of the reliability block diagram (Reliability Block Diagram) and the N-1 / N-2 criterion. Through the present invention, it is possible to obtain and evaluate the reliability of the power communication network, which reflects the reliability of the power service carried by the power communication network, the connectivity between any two nodes, the key / weak nodes, the key / weak links, and the recommended link with the optimal reliability. Several key indicators of sex.

[0019] The implementation process of the present invention is set forth in detail below: please refer to figure 1 , the present invention pre-establishes the network topology based on the path tracing algorithm, and pre-sets the reliability parameters of each node (the node reliability parameters may include par...

Abstract

The invention provides a method for evaluating the reliability of an electric force communication network, which comprises: based on a route track arithmetic, searching all paths between network topology source nodes and target nodes in a pre-established network topology, and defining the reliability degree of system network as union set of reliability degree of each path; defining the number of reliability expressions of recursive function calculation path set, and establishing a reliability expression array for the path set according to the number of the reliability expressions, wherein the path set is a collection of all paths, the recursive function is f(n)=f(n-1)*2+1, n is the number of path set. The reliability degree of the path set is calculated according to the reliability expression array and the reliability parameter of the pre-set network node. The reliability of an electric power communication net is estimated according to the reliability degree. Through the invention the reliability of the electric power communication net is effectively estimated.

Description

technical field [0001] The invention relates to a reliability evaluation method of a communication network, in particular to a reliability evaluation method of an electric power communication network. Background technique [0002] A sound and reliable power communication network is the basis for the safe and stable operation of the power system. A reliable power communication network should meet the following basic requirements: [0003] Can meet the reliability needs of various power services: [0004] Under normal circumstances, any two network nodes in the communication network must maintain the connectivity of at least two independent physical routes; [0005] If any network node fails and disconnects, it should be able to maintain the stable operation of the power service without causing communication quality degradation and channel congestion to other nodes; try to ensure that when any two network nodes fail and disconnect, it will not affect the normal operation of ...
