| Abstract: | In view of such problems as voltage fluctuation and harmonic pollution of the electric locomotive power supply system,the static var compensator(SVG)is used to improve the power quality of the power supply system.The working principle of SVG and its application in electric locomotive power supply system are analyzed in detail.The detection method of compensation current and the control algorithm of compre⁃hensive compensation in single phase system are proposed.The performance of electric locomotive power supply system with SVG is analyzed through simulation.It is shown by the result that the compensation de⁃vice SVG has such advantages as fast response speed,wide adjustment range,good harmonic suppression effect and small footprint.It can effectively solve the power quality problems in the electric locomotive pow⁃er supply system and improve the power quality. |
