Switched reluctance generator (SRG) is a new research direction for aircraft power system, and multi-generator grid-connected plays an important role in electrical power system of aircraft. To achieve stable output power grid-connecting, amplitude, phase and frequency of the output voltage are consistent with the value in the main bus. In the processing of grid-connected conversion, the power can be gotten, which is expected by using the method of space vector pulse width modulation (SVPWM) to control the block of three-level inverter in SRG power system. Simulation results show that the output power of grid-connected inverter output in the generator system is stable and reliable, achieve the grid-connected anticipation, and lower output voltage ripple.%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.
