Calculations of power system electromechanical eigenvalues based on analysis of instantaneous power waveforms at different disturbances

作者：

Highlights：

• A method for analysis of the power system angular stability is proposed.

• The stability can be assessed on the basis of the system state matrix eigenvalues.

• The eigenvalues are calculated based on the instantaneous power waveforms.

• The calculation method is based on the approximation of the transient waveforms.
