【Abstract】 First, the importance of synchronized sampling based on GPS for power system is introduced. Second. the generalscheme of GPS-synchronized sampling unit developed by the authors is presented. Then, the design scheme of each part ofthe GPS-synchronized sampling unit is presented in detail. Finally, Some practical applications of this unit to the faultlocation and parameter measurement of transmission lines in power system are described. which shows that this unit canassure high accuracy synchronized sampling for power system.更多还原
