  1. 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

    交流勵磁發機的基本結構與繞式異步機相同,其定子側接網,轉子上採用三相對稱分佈的勵磁繞組,由變器提供對稱交流勵磁,且勵磁壓的幅值大小、、相位、相序都可根據要求加以控制,從而可以控制發機勵磁磁場大小、相對于轉子的位置和機的轉速,使得交流勵磁發機具有良好的穩定性及轉速適應能力、獨立的有功與功調節能力和較強的進相運行能力,性能越傳統同步發機和感應發機,因而有著廣闊的應用前景。
