【Abstract】 The relationships among parameters of a delta-connected three-phase self-excited induction generator under single-phase steady-state operation are given to investigate the effect of self-excited capacitance on the built up terminal voltage.Based on the symmetrical component method and by means of matrix analysis,the loop impedance of induction generator under single-phase no-load steady-state operation is derived;regarding the zero loop impedance as the steady-state operation condition of induction generator,the equations are solved by alternative coordinate optimization and the value of no-load voltage is calculated.The applied calculation method is easy to program and stable.The no-load voltage values built up under various self-excited capacitances are calculated and the calculated values are close to experimental results,thus the effectiveness and accuracy of the proposed analysis method are validated.更多还原
