Study on the Impact of Grid Harmonic Voltage on SVG and the Suppression

Industrial Static Var Generator (SVG) is typically applied at or near the load center to mitigate voltage fluctuation, flicker, phase unbalance, non-sine distortion or other load-related disturbance. Special attention is paid to the influence of grid harmonic on SVG current, the harmonic grid voltage causes not only the AC current distortion but also the DC voltage fluctuation. The harmonic voltage decomposition algorithm and DC voltage control are also introduced. All these analyses can guide the practical applications. The simulation results verify the feasibility and effectiveness of the present control strategy and analyses.
