The Working Characteristics of the SVG in Low-Voltage Distribution System

The working characteristics of Static vargenerator(SVG) used in low-voltage distribution system is analyzed. The dynamic mathematic model based on direct current control is build by state space equations. The relation of the compensation performance and parameter is analyzed by the model as SVG used in low-voltage distribution system. The control method of voltage fluctuation compensation by using SVG as voltage source is proposed. Simulation and experiment results verify the correctness and validity of the mathematic model and control method.
