摘要
比较了双馈电机的两种启动方案,分析了电机定子侧电源的幅值及转子侧励磁电源的幅值、频率对双馈电机过渡过程的影响,并探讨了励磁电源的频率与牵入双馈状态允许的最大转差之间的关系。分别以电机的定、转子同步转速为参考,得出转子侧的不同频率对最大转差的影响及存在的规律性。该研究对于双馈电机的启动过程及调速工作都有着非常重要的意义。
Compared two starting methods of double-fed motor, analyzed the influence of the amplitude of the power in the stator and the amplitude/frequency of excitation power in the rotor on the transient process of double-fed motor, and discussed the relationship between the frequency of the excitation power and the maxi- mum speed difference when pulling into the double-fed state. Taking the motor＇s synchronous speed in the sta- tor and rotor as the reference respectively, the impact and regularity of different frequencies of the rotor side on the maximum speed difference was obtained. This study is of crucial significance to the starting process and speed governing of double-fed motor.
