| description | The invention discloses an on-line automatic identification method for a power grid oscillation mode type and an associated dispatching area, and belongs to the technical field of electrical power system calculation and analysis. According to the on-line automatic identification method, an intranet mode and an extranet mode as well as a local oscillation mode and a dispatching area oscillation mode can be distinguished, and the associated dispatching area of the oscillation mode is identified by aiming at each mode obtained by the dynamic stability analysis of small disturbance and a leading mode under each fault, which is obtained by the dynamic stability analysis of big disturbance; leading mode information is only extracted from an active-curve unit of which the amplitude is more than an appointed threshold value; a time domain simulation curve is sampled according to the frequency of the leading mode; and the calculation speed of the participation factor and the phase of the unit under the leading mode in |
