Research and Application of Low Frequency Oscillation Monitoring and Analysis Method Based on WAMS

A low frequency oscillation on-line monitoring and oscillation characteristics off-line analysis function module of power system based on wide area measurement systems was designed and implemented.Due to data filtering and other three detection algorithm were integrated into the on-line part of this module,real-time of monitoring and high precision of alarm are satisfied simultaneously.Due to improved Prony and other two analysis algorithm were integrated into the off-line part of this module,oscillation characteristics references were analysis comprehensively.The alarm record and data analysis results were saved on hard disk for deep mining of data information by the statistical function of this module.This module has been put into actual operation.The reliability and validity of it has been observed.
