开关磁阻发电系统是航空电源发展的新方向,多发电机并网供电在航空电源系统中占有重要地位。为了实现输出电能平稳并网,需要输出电压在幅值、相位和频率上与主汇流条电压保持一致;在汇流条并网电压的变换过程中,采用空间矢量脉宽调制(SVPWM)波控制开关磁阻发电机的三电平逆变器输出模块,即可得到满足要求的电能。仿真实验表明,该发电系统并网逆变单元输出的电压稳定、可靠,实现了平稳、准确的并网要求,且输出电压纹波小。
Switched reluctance power generation system is the new direction of the development of aviation power generation, multi-generator grid power supply in the aviation power system occupies an important position. In order to realize smooth grid connection of the output power, the output voltage is required to be consistent with the voltage of the main busbar in terms of amplitude, phase and frequency. In the conversion process of the bus voltage, the space vector pulse width modulation (SVPWM) wave control switch Reluctance generator three-level inverter output module, you can get to meet the requirements of electrical energy. The simulation results show that the output voltage of the grid-connected inverter of the power generation system is stable and reliable, and the requirements of smooth grid connection and accurate grid connection are achieved, and the output voltage ripple is small.
