Abstract: Aiming at the problem that the location of current residual current faults in rural power network is difficult to determine, this paper raised an online monitoring system of current residual current in rural power network with a kind of comprehensive ZigBee and general packet radio service (GPRS) network technology. The residual current and voltage in rural users were monitored in real time through the residual current transducer, ZigBee self-networking technology and GPRS technology. This paper designed a collector with the residual current transducer, IPC microcomputer and CC2530 chip and the concentrator was designed using CC2530 chip, ATM chip and GPRS module. The data between collector and concentrator was transferred through the Mesh network constructed by ZigBee. The data between concentrator and Web server was transferred through the GPRS network. The developed system can carry out long-distance wireless monitoring for the residual current in rural power network effectively.
Key words: rural power network; residual current; online monitoring system; ZigBee; general packet radio service
