Abstract：
 The invention is an energy quality controller for a traction power substation, composed of a three-phase converter and a Scott transformer, two orthogonal single-phase output power supplies are connected with two single-phase output ends of the Scott transformer, respectively, the three-phase converter connects in series with a three-phase output end of the Scott transformer, where the three-phase converter is an inverter with capacitor in parallel with the DC bus. It controls two power supply arms of the traction transformer at the same time and can effectively compensate harmonics in drawing electric network, reactive power and negative sequence current.
