Abstract

The invention discloses a node fault detection method of a power communication network. On the basis of a gray prediction method, a heartbeat strategy is introduced into node fault detection of the power communication network, and state change of a network node system is predicted dynamically; and an obtained dynamic prediction sequence of the network node system is taken as basis, a fuzzy algorithm is used to process fault signal delay of network nodes, and an output value sequence of fault detection signals of the network nodes is calculated. According to the method, the average error rate of fault detection is much lower than that of a fuzzy clustering algorithm because that state change of the network node system is predicted dynamically during fault detection and the correctness of the improved algorithm in network node fault detection is ensured; and during fault detection, the fuzzy algorithm is used to make the fault signal delay fuzzy, and thus, the time efficiency of the improved algorithm in fault detection for multimedia network nodes is ensured effectively.

Description

technical field [0001] The invention relates to a power system fault detection method, in particular to a node fault detection method of a power communication network. Background technique [0002] The current power communication network environment is characterized by heterogeneity, large network scale, distributed deployment, and frequent changes in network structure and status. When the power communication network node fails, it will easily lead to the disorder of key business applications of the power grid, and bring huge losses to people's life and production. Therefore, effective fault detection of power communication network nodes is one of the important ways to solve the above problems. [0003] When the current algorithm detects the faults of multimedia network nodes, it does not consider the delay of network node faults, which leads to large errors in node fault detection. To solve this problem, the application of the present invention proposes a node fault detec...
