Novel electric main wiring of transformer substation

The utility model provides a novel electric main wiring of transformer substation, including at least one power electronic transformer, the high voltage generating line is gone into to power electronic transformer's high voltage side joint, power electronic transformer's low pressure exchanges the side joint and goes into low voltage AC bus, follows power electronic transformer's middle and low voltage direct current [electronic] AC convertor draws forth the low pressure direct current and inclines, and then by the low pressure dc bus is drawn forth to low pressure direct current side. Through the low pressure dc bus inserts the DC load equipment or DC power supply, realizes flexible access and the hybrid power supply to hand over direct -current load of transformer substation to the DC load or energy storage equipment. 本实用新型提供种变电站的新型电气主接线，包括至少个电力电子变压器，所述电力电子变压器的高压交流侧接入高压交流母线，所述电力电子变压器的低压交流侧接入低压交流母线，从所述电力电子变压器的中低压直流-交流变流器引出低压直流侧，进而由所述低压直流侧引出低压直流母线。通过所述低压直流母线接入直流负载设备或直流电源，实现变电站对直流负载或储能设备的灵活接入和对交直流负荷的混合供电。
