基于励磁调压特性的交流同步电机强励控制

为了探索励磁调压特性对交流同步电机强励的控制关系,通过励磁EEAC理论从励磁调压角度对交流同步电机的强励控制进行分析,应用Matlab系统建立自并励单机仿真模型,并仿真分析了暂态过程中机端电压对交流同步电机强励的调控关系.结果表明,机端电压决定着电功功率,电磁功率决定着系统暂态稳定的裕度.在忽略损耗的条件下,电功功率等价于电磁功率,因而机端电压决定着励磁系统暂态稳定的裕度.

Forced excitation control of AC synchronous motor based on excitation regulation characteristics

In order to explore the relationship of excitation voltage regulation characteristics to the forced excitation control of AC synchronous motor, the forced excitation of AC synchronous motor was analyzed from the point of excitation voltage regulation through the excitation EEAC theory. The simulation model for the self-excited single motor was established with Matlab system. In addition, the regulation relationship of terminal voltage to the forced excitation of AC synchronous motor in the transient process was simulated and analyzed. The results show that the terminal voltage determines the electric power, and the electromagnetic power determines the margin of system transient stability. Under the condition of ignoring the loss, the electric power is equivalent to the electromagnetic power, and thus the terminal voltage determines the margin of excitation system transient stability.
