摘要
描述交流励磁工频同步化调速电机的结构,对其矢量控制系统、循环变流器、交流励磁工频同步化调速电机进行了仿真数值分析.结果表明,变频侧定子力矩电流在突加负载时仅有微小变化,速度响应的超调量也比较小,电机工频侧定子磁链比较平滑,未受动态过程的影响,具有较强的鲁棒性.仿真分析与实验结果达到较好的吻合.
The key structure of an Ac excited grid frequency synchronized machine (AEGFSM) was presented. The simulation of AEGFSM, cyclo-converter, field-oriented vector control algorithm was done according to their discrete mathematical model. An AEGFSM sample drived was fabricated. Simulation results are in excellent agreement with the experimental under the typical working condition. It is concluded that AEGFSM drives have the high-quality dynamic performances as DC drives and provide an applicable solution of middle-voltage freqency-variable drives.
