Lyapunov Stability Analysis for Self-Excitation of Induction Generators
Based on Lyapunov stability theory,a holistic analysis approach is proposed for self-excited induction generator under no-load in the stationary reference frame with the transient mathematic model.Through analysis for initial transient states,a sufficient condition is fixed to be the limit cycle.The analytic formulas of the stator frequency,critical excitation capacitance and critical rotor speed are thus obtained.The self-excitation build-up can then be judged.Good agreement between measured values and calculated values verifies accuracy and validity of the critical analytic formulas,showing generality and engineering application value.
