本文分别提出了在直流侧和交流侧启动过程中对模块化多电平换流器(MMC)的子模块(SM)电容进行完全充电的两种闭环预充电控制方法。所提出的方法旨在调节恒定的充电电流,从而减少启动时间和消除浪涌电流。此外,电容器电压平衡控制也嵌入到控制器中,平均充电的SM电容器。由于闭环控制的灵活性,这些方法适用于任何MMC应用,而不管SM的数量。最后,在一台三相MMC样机上验证了所提方法的有效性。
This letter respectively presents two closed-loop precharge control methods to fully charge the submodule (SM) capacitors of the modular multilevel converter (MMC) during dc-side and ac-side start-up processes. The proposed methods are aimed at regulating a constant charging current thus reducing the start-up time and eliminating the inrush current. Besides, capacitor voltage balancing control is also embedded into the controller to equally charge the SM capacitors. Due to the flexibility of the closed-loop control, these methods are applicable to any MMC applications regardless of the number of SMs. Finally, effectiveness of the proposed methods is verified experimentally on a three-phase prototype of MMC.
