摘要/Abstract

摘要： 为解决模块化多电平换流器（modular multilevel converter，MMC）输出电流畸变问题，提出一种中压直流配电网MMC的无差拍电流控制策略。该策略在每个控制周期内根据交流侧实际电流和参考电流的差值计算通断子模块的数量，使MMC能够在子模块开关次数较低的情况下增加电平切换频率。同时，所提策略无需比例积分调节（proportional integral control，PI），且减少了坐标变换次数，具有较快的计算速度。

关键词: 模块化多电平换流器, 中压直流配电网, 无差拍电流控制, 电流畸变

Abstract: In order to solve the problem of current distortion of the modular multilevel converter (MMC), this paper proposes the deadbeat control strategy for the medium voltage MMC. In each control period, the strategy calculates the number of on-off sub-modules according to the difference between the actual and reference AC current, so the MMC can increase its switching frequency with low switching times. At the same time, the proposed strategy needs no proportional integral (PI) control and fewer times of coordinate transformation, so it has the faster speed of calculation.

Key words: modular multilevel converter, medium voltage DC distribution network, deadbeat current control, current distortion
