摘要

在BESS和STATCOM等经典变换器问题中，采用多电平模块级联变换器(MMCC)可以提供更高的有效开关频率并降低谐波失真。为了在STATCOM应用中成功实现MMCC，有必要平衡各个模块的直流链路电压并跟踪参考输出电流。这项工作提出了利用反馈线性化和滑模控制的主模块和单个模块控制。仿真结果表明，本文提出的控制策略可以平衡各个模块的直流电压，并在第一个周期内提供输出电流跟踪。

Distributed control scheme for a 5-level modular multilevel STATCOM

Multilevel Modular Cascade Converters (MMCC) can be used to provide higher effective switching frequencies and reduce harmonic distortion in classical converter problems such as BESS and STATCOM. To successfully implement a MMCC in a STATCOM application it is necessary to balance dc-link voltages of the individual modules and track a reference output current. This work presents master and individual module controls utilizing feedback linearization and sliding mode control. Simulation results demonstrate that the control strategy presented in this paper can balance dc-link voltages of individual modules and provide output current tracking within the first cycle.
