摘要
通过构建变速式恒频感应发电机的数学模型,模拟电网电压在不同跌落状况和运行状态下电机的暂态工作过程,通过发电机端部效应的常值计算,解析暂态工作过程中电动机内各电磁量的变化。模拟结果显示,定子端部漏感对定子暂态磁链负面影响较大。该研究结论可为制定提高低电压穿越能力的控制策略提供参考。
The mathematical model of variable speed constant frequency induction generator is constructed to simulate the transient working process of the motor under different drop conditions and running state of the grid voltage. The change of electromagnetic quantity in the motor during the transient working process is analyzed by calculating the constant value of the generator end effect. The simulation results show that the stator end leakage has a great negative effect on the stator transient flux,which provides a reference for the establishment of the control strategy to improve the low voltage crossing ability.
