DC Voltage Balance Control Strategy for Medium Voltage Cascaded STATCOM Based on Distributed Control

open access: yesJournal of Networks, 2014
DC bus capacitors of Medium Voltage Cascaded STATCOM are independent. DC side voltage balance control method is the key influencing factor of current control. The imbalance of DC bus voltage increases harmonic current and affects the safety of device. In this paper, the unbalance mechanism of DC side capacitor voltage is analyzed. Based on the unipolar
