Fault analysis method and system for power communication network

Abstract

The present invention provides a fault analysis method for a power communication network, which includes the following steps: S1, constructing a power communication network model and its corresponding topology diagram and power communication cabinet model diagram, and selecting at least one resource object in the topology diagram and Select at least one resource object in the power communication cabinet model diagram to set a fault point; S2, set an event for the physical device corresponding to the power communication network model, so that the physical device with the event set is in a normal working state or in an abnormal working state; S3, judge Whether there is a power supply device in the set fault point, if so, judge the fault status of all communication devices powered by the power supply device according to the fault judgment rule set, and then judge the fault status of communication devices powered by other power supply devices and their Fault status of the carried service. The invention covers a wide range of resource objects and can help to give correct and effective prediction results of power communication network failures.

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
