摘　　要：本文对角接三相自励异步发电机单相稳态空载建压过程进行了分析。用对称分量法求出发电机不对称稳态运行时的回路阻抗,令回路阻抗的实部与虚部分别为零,作为异步发电机稳态运行的条件,由此计算给定电容值情况下的空载电压值。计算过程中用Hooke- Jeeves提出的模式搜索法求解有约束优化问题,此法比传统的Newton-Raphson法稳定性好且编程简单。论文给出了空载时给定不同电容值所建立的空载电压值,同时对计算结果进行了分析。This paper analyzes no - load voltage building process of a A - connected three - phase induction generator under single - phase operation. The loop impedance is derived using the symmetrical component method. With both real and imaginary parts of the loop impedance equal to zero, the equations for steady - state operation are established to calculate the performance. The direct search method advocated by Hooke -Jeeves is used to solve the optimization problem, which is simpler and more effective than Newton - Raphosn method. The calculated building voltages at different capacitances are given for no - load operation and the results are analyzed.
