In order to improve the power quality of traction power supply system of electrified railway

an experimental platform for comprehensive control of power quality of electrified railway is designed to save a lot of manpower and material resources and improve the research efficiency of scientific researchers.Since many kinds of power quality control equipment take PWM converter structure is basis and on the basis of the need of experiment function of electrical quality control equipment of present electrified railway with combination of connection and distinction of multiple electro electronic experiment topology structure and control mode

the overall structure and main electric circuit are designed

the principle and method of experimental mode transfer is given and the software and hardware experiment platform is set up for function verification.The correctness and effectiveness of the power quality comprehensive control platform of the designed electrified railway is verified by the experiment result.
