Fault analysis method and system for an electric power communication network

Abstract

The invention provides a fault analysis method for an electric power communication network. The method comprises the following steps: S1, constructing an electric power communication network model anda topological graph and an electric power communication cabinet model graph corresponding to the electric power communication network model, selecting at least one resource object from the topological graph, and selecting at least one resource object from the electric power communication cabinet model graph to set a fault point; S2, setting an event for entity equipment corresponding to the electric power communication network model, and enabling the entity equipment with the set event to be in a normal working state or an abnormal working state; And S3, judging whether power supply equipmentexists in the set fault point or not, if yes, judging the fault states of all communication equipment powered by the power supply equipment according to a set fault judgment rule, and then judging the fault states of the communication equipment powered by other power supply equipment and the fault states of services borne by the communication equipment. The method covers a wide range of resourceobjects, and can help to give a correct and effective power communication network fault prediction result.

Description

technical field [0001] The invention relates to the field of electric power technology, in particular to a fault analysis method and system for a power communication network. Background technique [0002] As the scale of the power communication network becomes larger and the scale of equipment increases, the subsequent risk of system failure poses challenges to the risk management and emergency response capabilities of operation and maintenance managers. In order to ensure the safe, effective and stable operation of the power communication network, it is necessary to simulate the faults that may occur in the circuit communication network in advance, and simulate the impact of foreseeable faults on the services carried by the power communication network, so as to facilitate the maintenance personnel of the power communication network Set up emergency plans to effectively deal with the risk of failure in the operation of the power communication network. The resource objects c...

Problems solved by technology

The resource objects covered by the N-1 analysis method currently implemented by the resource system are not enough. The N-1 analysis of many facilities and equipment still requires manpower estimation and analysis. Fault analysis only for a single type of resource object is no longer sufficient for large-scale equipment operation and maintenance. Management requirements, the accuracy of fault location and emergency response efficiency of conventional N-1 analysis can no longer meet the needs of the development of power communication networks
