Stability Assessment Approach Based on Trajectory Section Eigenvalue

Eigenvalue Method can analyze the operating features of system. The trajectory section eigenvalue method combines model and trajectory, extends equilibrium point to unbalanced cross at any time on disturbed which well solves non-linearity time-varying issues Based theoretical basis clarifying (TSE) method, paper establishes a stability evaluation framework based second-order resonant circuit, extrates damping feature frequency information in sequence section, then compares it with results signal processing. influence mechanism factors system is clarified, advantages are demonstrated.
