Abstract
The concept of smart grid has been proposed for years. Many countries, such as United State, England and Japan, have been replacing traditional electric meters with smart electric meters in recent years. There are lots of communication methods used in smart grid, power line communication (PLC) is an important one among them. G3-PLC is a widely-used specification for long-distance PLC, however, PLC is sensitive to old power lines and the interference caused by large electric current flowing through the power line. Moreover, although G3-PLC has stable performance of communication, the AODV routing protocol and the complex startup procedures results in taking long time for G3-PLC devices to finish the whole startup procedures.
To reduce the time to finish the startup procedures in G3-PLC, in this paper, a tree topology algorithm is proposed. In the tree topology algorithm, a simple startup procedure is provided, by setting up the parent-child relationship between nodes, the routes for nodes in networks are simplified. Furthermore, a maintain procedure is also provide in the algorithm, in the maintain procedure, the nodes in networks can use Check Alive mechanism to check the connection between their parent nodes and child nodes, when a broken connection is found by a node, the node will use Recovery mechanism to rescue the isolated nodes.
In this paper, the feasibility of the tree topology algorithm is verified by NS-3 platform, and suggestions of the suitable value of the parameters in the algorithm are proposed. In addition, the algorithm is implemented on Atmel SAM4CP16C evolution kits, the measurement results show that the time for PLC devices to finish the startup procedures of the tree topology algorithm is at least 6.7 times less than G3-PLC specification.
