| 摘 要： | 在双馈发电机等值电路的基础上,建立了相应的基本方程,并求出定子电流的解析表达式.通过对定子电流的分析,求得输出电流为额定值时的励磁电压有效值解析表达式及初相位的取值范围.在此基础上,通过对定子电流有功分量及无功分量的分析,得到功率因数超前及功率因数滞后时的励磁电压初相位取值范围.为满足实际工程需要,对电机的参数作进一步简化,最终通过电机的实际参数进行仿真,验证了其理论分析的正确性.

| Abstract: | Based on the double feedback generator equivalent circuit,the corresponding fundamental equation has been established,and the analytic expression of the stator current has also been extracted.Through the analysis on the stator current,the analytic expression of the valid value of the excitation voltage and the scope of the initial phase value have been extracted when the output is at the rated value.Based on this,through the analysis on the active component and the reactive component of the stator current,t... |
