Abstract
A monitoring system of rural power grids based on GPRS was designed.In this system,the difference of frequence and phase was measured via the internal timer of MCU STC12C5410AD.The normal running information and fault information through GPRS wireless communication module would be sent to data center by instantaneous sample of effective value voltage and current to cooperate with sampling,magnifying,precision rectifier and filter circuit.The system had features such as small volume,low price,low power consumption,convenience,stability and reliability.It would be an effective solution to remote monitoring of parameters of power system.
