摘要：

针对模块化多电平变流器(MMC)的直流侧电压启动不对称问题,分析该情况启动失败导致的原因.提出新的启动策略,该策略相对于传统的启动方法具有三相对称性好、速度快且不容易启动失败等优点.对模块化多电平变流器载波移相控制下直流电压的二级控制进行严格的数学建模,分别推导子模块电压平均控制和平衡控制环的传递函数，并介绍相应控制器的设计方法.利用Matlab搭建仿真模型,验证了所提出启动策略、数学模型以及控制器参数设计的正确性.
Abstract:

The causes of potential start failure were studied aiming at the unsymmetry problem of the modular multilevel converter (MMC) DC voltage starting.  A new starting method was proposed, which is three phase symmetrical, time saving and can avoid start failure effectively. A precise mathematical model of the system was deduced for the sub module voltage average and balancing control of MMC in the modulation of phase shifted control (PSC). The transfer function and the designing of voltage controller parameter were  analyzed. A model  built in Matlab simulation  verified the feasibility of the proposed starting strategy, the correctness of the mathematical model and the designing method for DC voltage controller．
