摘　　要：分析了多模块矩阵变换器(MMMC)双电压合成控制策略的原理,并对其抗电网扰动性能进行分析研究。通过Matlab/Simulink进行仿真研究,得到的电压谐波畸变率与基波幅值几乎没有变化。试验表明,MMMC双电压合成控制策略具备自动修正能力,对电网具有抗扰动能力。This paper analyzed the principle of two line voltage synthesis control strategy of multi-modular matrix converter （MMMC） and the ability to resist disturbance. The simulation model was set up in MATLAB/ simulink based on this modulation strategy. The fundamental amplitude and voltage harmonic distortion rate almost keep constant. The experiments show that the dual line to line voltage synthetic control strategy of MMMC possesses adaptive ability and can resist power grid disturbance.
