With disturbance source system and its location based on data off-line

The present invention relates to the field of real-time dynamic monitoring and stabilization POWER SYSTEMS, particularly, to a source of the disturbance system and its location based on data off-line. The present invention provides a low frequency oscillation monitoring the source of the disturbance positioning system offline, the present invention may be utilized BPA stable calculating output data and historical repository data disturbance during recording, data interfaces according disturbance positioning function requirements, the internal data into identifiable data model, while using cut set location algorithm calculation, to achieve the disturbance source localization key areas, the disturbance source localization apparatus stage positioning and control stage key unit, and to achieve the disturbance source location information display, low frequency oscillation mode information display and cut sets calculation results show.
