摘　　要：为了扩大静止无功发生器的补偿容量和减少交流侧的输出谐波,本文采用了级联多电平的主电路结构,并使用了载波移相技术的方法对其进行调制;最后在Matlab上搭建了基于载波移相技术的静止无功发生器的仿真,仿真结果表明采用载波移相调制方法谐波输出含量少,整个系统也能很好的补偿系统的无功电流。In order to expand the STATCOM compensation capacity and reducing the AC side output harmonic wave, this paper employs a cascaded multilevel structure of the main circuit, and the use of carrier phase shi^t technique approach to its modulation; finally it was built based on carrier phase shift technique of STATCOM simulation in Matlab, the simulation results show that the use of carrier phase modulation method for harmonic output content is little, the whole system can be very good for the reactive current compensation system.
