Analysis of electrical load characteristics of HXD1B locomotive based on measured data

This paper firstly introduces the main circuit of traction drive system of HX
D
1B locomotive, and gives the operating principle of a single phase four-quadrant PWM rectifier. Then based on measured data, the power factor and harmonics characteristics of HX
D
1B are analyzed. The statistical rules on the power factor and harmonic contents are summarized, which can be used to build a probabilistic model for the HX
D
1B locomotive.
