Analysis of Self-excited Voltage Building of High-low Voltage Dual Stator-winding Induction Generator Considering Mutual Leakage Inductance

The transient analysis of self-excited voltage building of high-low voltage dual stator-winding induction generator system is carried out by using eigenvalue analysis method. Based on the transient equivalent circuit considering the mutual leakage inductance between stator windings, the state equation of the system is deduced and the eigenvalues of the system are solved. According to the one-dimensional blind-walking optimization method, the minimum capacitance required for voltage building of generator system is calculated, and the accuracy of the results is verified by comparison with other methods. The transient waveforms of generator voltage building are obtained by simulation. The experimental waveforms are consistent with the simulation results, which shows the effectiveness of the method.
