| 摘 要： | 为方便航空供电系统交流负载用电性能的研究,提出了交流负载的半实物仿真技术.以电压型脉冲宽度调制整流拓扑结构和三相电流的解耦控制为基础,采用复合补偿结构保证快速性;增加一组桥臂为中线电流提供通路;在电网端加入滤波器滤除开关谐波以得到更真实的负载特性.交流负载的半实物仿真技术在115 V,400 Hz的航空电源系统中实现了网侧电流跟踪上位机数字仿真后的给定电流的功能,模拟了交流负载的功率因数、电流谐波和不平衡性的动态变化过程.通过仿真实验结果表明了提出的半实物仿真技术的精度和快速性都达到了要求,为航空供电系统交流负载用电性能的研究提供了工具.

| Abstract: | To facilitate alternating current(AC) load power performance research in aircraft electric power system,the AC load semi-physical simulation technology was proposed.The technology was based on pulse width modulation rectifier topology and three-phase current decoupling control.Complex compensation structure was used to ensure rapid tracking;a one-leg was added to provide access to the neutral current;the power filter was added to reduce the switch harmonic current for obtaining the more real load characteri... |
