Abstract
In modern power systems, the methods of voltage sag monitors optimal placement and fault assessment are based on fixed threshold detection system, which affect the method's accuracy. To change this limitation, an active information extraction on-line monitoring system for voltage sag is developed. The monitor is based on STM32 microcontroller chip, using GPRS to communicate with the host computer. A new monitor reach area method considering fault location is proposed. LabVIEW is used to build servers. The host computer uses a new fault location method to analyze the uploaded information. The simulation results show that the new design of the system can accurately locate the fault location and evaluate the voltage sag state of the network.
