一种基于采样延迟补偿的MMC电压测量新方法

The nearest level control is suitable for modular multilevel converter (MMC) with large number of submodules (SM). The voltage measure method for MMC requires to install a voltage sensor for each SM, which increases the system costs and the burden of the data acquisition system. This paper presents a novel voltage measure method to solve this problem. With the proposed method, the SMs are divided ...
