| Abstract: | The relationship between complex torque coefficients and eigenvalues in subsynchronous resonance analysis isderived by using the complex variable function thoery. The thoeretical basis and the utilization conditions of thecomplex torque coefficient method are established. Furthermore, based on the frequency scan results. an estimation algorithm of eigenvalues corresponding to the subsynchronous resonance modes is proposed. Simulations on IEEE first benchmark system show that the estimated eigenvalues are well consistent with their true values. |
