Abstract：Bearing the advantages of low operation cost,large transportation capacity fast running speed and energy saving,the electrified railway is also environmental friendly.However,as a high-power,non-linear and volatile heavy load,the electrified railway load is bound to bring a lot of adverse effects on the power quality in power system.After measuring the load data of Dazhun railway,a testing method has been introduced in this paper.Through analysis of electric current and voltage regulation in heavy freight substation,the characteristics of railway load are summarized.Problems along the railway location are discussed,and a simulation model of traction power supply system is thus established.On the basis of measured data,the effect of railway load characteristics and impact characteristics on power quality has been analyzed from three aspects including voltage deviation,negative sequence and harmonic.
