摘要:
针对模块化多电平变换器(MMC)的底层控制策略,提出了同相层叠正弦脉宽调制算法(PD-SPWM)。首先,建立了M M C 的控制模型,介绍了其运行特征;其次,从理论上分析了P D - S P W M 算法的实现过程,并在此基础上,进一步提出了桥臂子模块电容电压平衡控制算法;最后,在1.5 MW 的五电平MMC 柔性直流输电(MMCHVDC)样机上进行了相应的实验。试验结果表明所提出的调制算法有效,且是综合性能最优的MMC 调制算法。
Abstract:
It presented the algorithm of Phase Disposition Sinusoidal Pulse Width Modulation (PD-SPWM), aiming at the apparatuslevel controller of modular multilevel converter(MMC). Firstly, it established a control model of MMC, and introduced its operating characteristics. Secondly, the implementation process of the PD-SPWM algorithm was theoretically analyzed, furthermore, the bridge submodule capacitor voltage balancing control strategy was proposed. At last, a series of tests were operated in the 5-level prototype. The test results show that the proposed modulation algorithm is effective, and has the best overall performance for MMC modulation.
