中文摘要	A new approach was developed to optimize the self-excited capacitance and to calculate the related no-load terminal voltage. The loop impedance expression was derived from the induction generator equivalent circuit referred to the base frequency. Setting both the real and imaginary parts of the loop impedance to zero gives the steady state performance of the induction generator, which can be used to determine the self-excited capacitance. The direct search method used to solve the constrained optimization problem is more flexible and stable than the Newton-Raphson method. The calculated self-excited capacitances for various terminal voltages are in good agreement with experimental values. The calculated results also verify the -effect of saturation on the no-load self-excited capacitances and show that the incremental increase of the self-excited capacitance is much greater than that of the saturation.
