Research On Networking Technology Of Distribution Monitoring Network

Electric distribution network is part of the electricity network that directly supplies power to consumers; its normal operation is the crucial element in the operation of the entire power system. With the construction and upgrading of the energy grids in urban and rural areas, the scale of the net is gradually expanding, partial failure affects broader, and the damage involved is greater. Thus the real-time monitoring of the distribution network operation has become a hotspot in the electricity sector.The networking technology regarding the specific requirements of power distribution monitoring network is studied, and it is mainly divided into two parts: First, the analysis and design of the scheme of networking the power distribution monitoring network is proposed, the layout scheme of the monitoring network at all levels is proposed, such as the electrical characteristics of the monitoring node, the access mechanism of the data link layer channel, network topology, design and optimization of the control center. Second part is the design of power distribution monitoring network routing protocols, which is based on the classic routing protocols available and the specific application requirements, we come to the tree-level heterogeneous monitoring network.By simulation, it's demonstrated that this networking scheme with low-cost which does not rely on the inherent infrastructure and other communications networks, can meet the requirement of real-time monitoring, reliability and stability of electric network distribution.
