This paper introduces the idea of applying wireless sensor network to remote on-line monitoring system of smart substation. The intelligent combined substation network scheme based on wireless sensor network and GPRS is given. The use of spe. cial CT and battery combination,which effectively solves the problem of insufficient power supply node sensor. Based on reducing the number of routing hops and improving transmission efficiency,a design idea of three-layer wireless sensor network architecture is proposed. The selection of sensors and the optimal layout of sensor nodes are discussed. The paper also puts forward the wireless sen. sor network technology applications exist in substation intelligent transformation,network security and clock synchronization issues.
