Abstract

Abstract:

In the cascaded H-bridge multilevel SVG(Static Var Generator), the inherent structural characteristics of the H-bridge lead to the presence of secondary ripple in the DC-side capacitor voltage of the angular cascaded SVG, and the voltage ripple affect the degree of compensation of power quality and even lead to system dysregulation. In order to suppress the secondary ripple of the voltage on the H-bridge DC side of the angular cascaded SVG, this study proposes a design solution for the angular cascaded H-bridge multilevel SVG based on Boost-type active power decoupling. The APD(Active Power Decoupling) circuit separates fluctuating power and stable power from each other and uses energy storage elements to absorb fluctuating power, which weakens the voltage ripple on the DC side of the H-bridge. The simulation platform was built and simulated using MATLAB/Simulink software. The simulation results show that the angular cascaded H-bridge multilevel SVG based on Boost-type active power decoupling can effectively suppress the secondary ripple of the voltage of the DC-side capacitor.

Key words: secondary ripple, triangular structure, SVG, reactive power compensation, active power decoupling, Boost, DC voltage, fluctuating power
