三相自励异步发电机稳态运行外特性的分析计算

以三相自励异步发电机等值电路为基础,令电路的回路阻抗为零,通过迭代的方法分析异步发电机的稳态运行性能并着重研究了外接电容、电机参数和转速对发电机外特性的影响。为计算方便,采用了降低求解方程次数的处理方法,计算结果与实验结果相互吻合说明了分析方法的正确性。仿真结果表明转子转速和自励电容值对外特性的影响较大;外特性中的端电压特性受参数的影响大,频率特性受参数的影响小。

Analysis of External Characteristics of Self-Excited Induction Generators

This paper proposes an iterative method based on equivalent circuit to predict the steady-state performances of the isolated self-excited induction generators. In the iterative process, the loop impedance is set to zero, which is the foundation for further analysis. For the convenience of computation, simplified technique for decreasing orders of the equations is utilized. Calculation results are compared with the experimental values, which show a good agreement between them. Much more, the emphasis is on t...
