为了满足飞机多电化对于航空发电系统提出的高功率密度、高品质供电以及交直流混合供电的要求,对比分析了多种交直流集成发电方案,并分析了其优势与不足,提出了一种基于双绕组感应发电机的航空交直流集成发电系统.该系统充分利用了双绕组感应发电机定子有两套三相绕组的特点,能够很好的实现交直流集成发电.在进行发电机初步设计后,基于多目标优化算法,以效率和功率密度为目标对双绕组感应发电机进行优化设计,采用交直流集成发电自抗扰控制策略,以提高该系统动态性能与负载适应性.最后研制了一台60kW(交流24kW,直流36 W)的双绕组感应发电机原理样机,实验结果显示,该交直流集成发电系统在交流侧突增、突卸负载时,电压突变在±10V以内,恢复时间不超过25 ms,在直流侧突增、突卸负载时,电压波动在±30 V以内,恢复时间不超过45 ms,具有良好的动态性能和稳态性能,能够实现发电系统的高品质交直流集成发电.研究成果表明,基于双绕组感应发电机的航空交直流集成发电系统有望为我国多电飞机发电系统提供一种有竞争力的可选方案.
AC-DC integrated aviation power generation system based on dual winding induction generator
In order to meet the requirements for high power density,high-quality power supply and AC-DC hybrid power supply for aviation power generation system proposed by aircraft multi-electrification,a variety of AC-DC integrated power generation schemes were compared,and their advantages and disadvantages were analyzed.An AC-DC integrated power generation system based on dual winding induction generator was proposed.The system made full use of the dual-winding induction generator stator with two sets of three-phase windings,so it can achieve a good AC-DC integrated power generation.After preliminary design of the generator,based on the multi-objective optimization algorithm,the dual-winding induction generator was optimized and designed with the objectives of efficiency and power density.An AC-DC integrated power generation control strategy based on active disturbance rejection control was adopted to improve the dynamic performance and load adaptability of the system.Finally,a generator of 60 kW(24 kW AC,36 kW DC)dual-winding induction generator principle prototype was developed,and the experimental results verified that when the AC side increased and offloaded abruptly,the voltage changed within±10 V and the recovery time was not more than 25 ms;when the DC side increased and offloaded abruptly,the voltage fluctuated within±30 V and the recovery time was not more than 45 ms.The system with good dynamic and steady-state performance can realize high-quality AC-DC integrated power generation.Research results showed that the aero-AC-DC integrated power generation system based on dual-winding induction generator is expected to provide a competitive alternative for the multi-electric aircraft power generation system.
