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

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 dual frequency and carrier phase-shifted S...

Current Decoupling Control Strategy of Medium Voltage Cascaded Multilevel STATCOM

As one of effective regulation methods, static synchronous compensator (STATCOM) has been widespread used to regulate dynamic reactive power and solve dynamic voltage stability problems into powergrid. Through the analysis of mathematical model, cascaded STATCOM, which is constructed by several cascaded H-bridges, is a nonlinear, multivariable, strongly coupled system. It will make difficulties...

Design of DC Voltage Control for D-STATCOM

This paper presents the DC voltage control design of D-STATCOM when the D-STATCOM is used for load voltage regulation. Although, the DC voltage can be controlled by active current of the D-STATCOM, reactive current still affects the DC voltage. To eliminate this effect, the control strategy with elimination effect of the reactive current is proposed and the results of the control with and witho...

A Design Approach for DC Voltage Controller of CHB-based STATCOM

In this paper, a novel parameter design approach of the PI controller used for individual DC voltage balancing control of cascaded H-bridge converter-based STATic synchronous COMpensator(STATCOM) is presented. By means of phase shift sinusoidal pulse width modulation, using two control loops(DC voltage control loop and phase angle shift control loop) to ensure DC voltage balance, the proposed a...
