A Novel Method for Voltage Sag Source Location Based on HHT and GA-BP

A Novel Method for Voltage Sag Source Location Based on HHT and GA-BP

Aiming at the low accuracy of traditional voltage sag source positioning methods, this paper proposes a new location method based on HHT and GA-BP. Firstly, the EEMD(ensemble empirical mode decomposition) Hilbert-Huang Transform (HHT) is used to process the voltage and current during the fault perio...
