Study on an Anti Power-Stealing Monitoring System for a Rural Power Grid in China

摘要

Power-stealing phenomena not only make the power industry suffer a tremendous economicnloss, but also threaten the security and reliability of some rural electric networks in China.nIn this paper, an anti power-stealing monitoring system is developed, which contains a remotenanti power-stealing terminal, a GPRS and Internet network, and a monitoring center. The antinpower-stealing terminals are developed based on STPM01 and module GR47, which are installednin remote villages to detect power-stealing and measure power consumption. Power comparisonnmethods and electricity energy comparison methods are used to confirm power-stealing. Informationnfrom anti power-stealing terminals is sent to the monitoring center through GPRS and thenInternet.nThe monitoring system now is in operation in the Qingtongxia rural electric network, and resultsnindicate that it is an effective way to discover power-stealing events using different power-stealingnmethods.
