    摘 要:针对传统正交磁化可控电抗器宽范围调磁时励磁功率较大,同时交流磁路与直流电路间存在耦合的情况,提出了一种基于直流记忆磁通的正交磁化可控电抗器。利用可反复冲去磁的铝镍钴永磁体代替直流激磁线圈产生直流磁通,并设计了交直流电路和磁路无耦合的新型正交磁路结构。仿真分析结果表明,该电抗器实现了直流磁路对交流磁路的单方向控制,使电抗器电感的控制调节更加简单。

    Abstract: Aiming at the condition that the exciting power is bigger when the orthogonal magnetizing controllable reactor adjusts the flux in wide range and there is coupling between the AC magnetic circuit and the DC circuit. This paper proposed a kind of orthogonal magnetizing controllable reactor based on DC memory flux. The aluminum nickel cobalt alloy (AlNiCo) magnet with low coercive force and high residual flux density was used so that the DC flux could be online tuned without additional copper loss. This paper designed the new type of orthogonality magnetic structure without coupling between the AC-DC circuit and magnetic circuit. The simulated analysis result shows that this electric reactor realizes the unidirectional control from the DC magnetic circuit to AC magnetic circuit, which makes the inductor of electric reactor controllable more easily.
    Key words: DC memory flux; orthogonal magnetizing controllable reactor; AlNiCo
