摘要：An idea of applying wireless sensor network and GPRS to intelligent package substation on-line monitoring system is brought to light in this paper. Network schemes of intelligent package substation are given based on wireless sensor network and GPRS. The detailed analysis has also been made on some key technologies. At the same time, the combination of special CT and accumulators is adopted to solve the power supply shortage of sensor nodes effectively. To reduce the routing hops and improve the transmission efficiency, the two-layer and three-cluster of network structure is used. Finally, the on-line monitoring system of transformer room is taken as an example, it is discussed how to obtained optimal layout of sensor nodes. The paper also points out which can be taken as the research focus in the future such as intellectualized reconstruction of package substation, network security and clock synchronization.
