| Along with the development of smart grid in China, distribution network as the connectors of users, distributed power and grid, will play an important role to the development of the smart grid. Intelligent distribution network is the important guarantee to realize the distribution automation, optimize the operation and support for the decision of grid. Due to the complex structure, extensive areas, various terminal of distribution network, how to make use of advanced communication technology to realize the intelligent distribution network is the key to the develop distribution network.Wireless sensing network is a new technology collect sensing and communication. WSN has been applied in many industries because of its low cost, simple layout and organized itself. In this paper, the background is intelligent distribution network, research on WSN routing protocol problems in power distribution network has been conducted.The classification and the communication need of intelligent distribution network business has been analyzed. According to the characteristics of the intelligent distribution network, three basic questions is proposed in intelligent distribution network. In view of the problems, TPGF algorithm hole has been analyzed. A new algorithm based on two steps is proposed to predict holes. And using the projection distance instead of greed steps forward, can effectively improve the energy utilization rate.On the basis of single path algorithm, the multipath routing algorithm based on intelligent distribution has been researched. Multipath tree is built based on multi-step forward, using distance and angle to select next node, and simplify in reverse direction. Function that selects transmission path is combined with node number,surplus energy and energy consumption to transmit single packet. Experiments show that the algorithm meets the communication demand of distribution network, and delay, living time has been optimized. |
