提出了静止同步补偿器中基于单星桥单元的模块化多电平级联变流器的平均功率平衡(APB)控制方法。该控制方法即使在电网电压暂降的情况下，也能同时实现无功补偿和直流母线电压平衡控制。随着越来越多的分布式发电资源并入电网，该方法的低压穿越能力将变得越来越重要。给出了实验室试验结果，验证了所提出的APB控制方法。
This paper presents the average power balancing (APB) control method for the modular multilevel cascaded converter based on single-star bridge cells in the static synchronous compensator applications. The proposed control method accomplishes both the reactive power compensation and the dc bus voltage balancing control even under grid voltage sags. The low-voltage ride-through capability of the proposed method will become more and more important as more distributed generation resources are integrated into the grid. Laboratory test results are provided to validate the proposed APB control method.
