Design of routing optimization for substation high voltage side monitoring system based on wireless sensor network

摘要

To meet the monitoring requirements of substation high voltage side, we adopt intelligent monitoring method based on wireless sensor network technology. For the power energy and communication distance of wireless sensor nodes are limited, this paper proposed a routing optimization design based on power control to ensure the reliability and lifecycle of the monitoring network. According to the characteristics of wireless sensor network topology in substation equipments high voltage side, the nodes set transmission power step-value, which perceived the information of adjacent nodes intelligently and set up the node information matrix. The proposed design adopted hierarchical routing protocol, chose the cluster head, and monitored information changes of adjacent node in the process of transmitting data to the next address, updated routing table information of network dynamically to achieve reliable data transmission and monitoring substation equipments high voltage side real time.
