Application of local-world evolving network model in power transmission and distribution network of Guizhou

According to the atlas of tidal current and data of electric network of Guizhou, we portray the connecting graphics of electricity transmission and distribution about each node of electric network. We take the advantage of the small-world networks, scale-free network and local-world evolving network model to analyse and validate the construction characteristic of electricity transmission and distribution network of Guizhou. Through on example the tidal atlas of electric network is divided in to 4 sections and 78 nodes. The comparison of calculation results of related data of scale distribution function of the local world evolving network model shows Guizhou distribution ret work accord with the local-wored evolving model, having the characteristics of the model. Monitoring and protection should be strengthened at the collecting and distributing node. It is necessary of further study the mechanism of failures to ensure the operational securing of the power network.
