The stator of aceg is connected to the grid and the three symmetrical excitation windings in the rotor are fed by converter . the magnitude and frequency and phase and phase sequence of excitation voltage can be controlled , so the magnitude and position of excitation mmf as well as the speed of rotor can be controlled . therefore , acegs have superior performances by contrast with conventional synchronous generators and induction generators , such as upstanding stability , power generation of variable speed constant frequency ( vscf ) , adjusting active power and reactive power independently , and absorbing lag reactive power deeply 交流励磁发电机的基本结构与绕线式异步电机相同,其定子侧接电网,转子上采用三相对称分布的励磁绕组,由变频器提供对称交流电励磁,且励磁电压的幅值大小、频率、相位、相序都可根据要求加以控制,从而可以控制发电机励磁磁场大小、相对于转子的位置和电机的转速,使得交流励磁发电机具有良好的稳定性及转速适应能力、独立的有功与无功调节能力和较强的进相运行能力,性能超越传统同步发电机和感应发电机,因而有着广阔的应用前景。
