H-bridge cascaded static var compensator (STATCOM) has many advantages, such as high voltage level, large equipment capacity, high equivalent switching frequency. But it is difficult to control phase voltage and capacitor voltage of each module of DC side, and this is an important reason for stopping to exert operating performance. So decentralized control strategy is proposed, and it is applied to the H-bridge cascaded static var compensator. This control strategy uses hardware architecture of combining PC with lower machine. PC control double-loop of voltage and current of AC side and lower machine achieves the balance control of capacitor voltage of each module of DC side. Results of simulation and experiment verify the effectiveness of the control strategy. © 2016, Xi'an High Voltage Apparatus Research Institute Co., Ltd. All right reserved. Source
