摘要:
介绍了模块化多电平换流器(modular multilevel converter,MMC)的运行原理以及模块电容电压的平衡控制。考虑传统的单相桥臂平均电压控制可能会在外部干扰的情况下输出电压不平衡而导致波形畸变,结合载波移相调制方法提出了三相桥臂平均电压控制的方法,并对子模块电容电压采取比例积分调节,使得模块电容电压平衡在稳定的范围内。仿真验证了电容电压平衡控制的可行性。
Abstract:
This paper introduces the operation principle of modular multilevel converter and balancing control method of capacitor voltage. Considering the condition under external disturbance which may lead to outputting unbalanced voltage and waveform distortion when using traditional single-phase bridge average voltage control, three-phase bridge average voltage control is proposed combined with carrier phase-shifting modulation. Proportion integral adjustment is adopted for sub-module capacitor voltage so that the modular capacitor voltage fluctuation can be maintained in a stable range. Simulation shows the feasibility of capacitor voltage balancing control.
