Out-phase and in-phase compatible integration compensation device of Vv wiring traction substation

The utility model discloses an out-phase and in-phase compatible integration compensation device of a Vv wiring traction substation. On a traction substation secondary edge, a look-ahead (T1-N) phase and a lag (T2-N) phase provide power for a traction load. Direct-current-side back-to-back first static reactive power generator SVG1 and an alternating current side of a second static reactive power generator SVG2 are connected with the look-ahead (T1-N) phase and the lag (T2-N) phase of the Vv traction substation respectively so as to form the integration compensation device in which an out-phase structure and an in-phase structure are compatible; and an out-phase mode is easy to develop and convert into an in-phase mode. A negative sequence trend which is opposite to a traction load is generated. Through reasonable control, reactive compensation and harmonic suppression are achieved. System utilization is flexible. Cophase power supply is easy to realize. Electrical phase splitting at an outlet of the traction
