摘　　要：为了在减少碳排放量的前提下提升边远台区用电质量,提出基于交直流并联结构的边远台区改造方法。引入电压源换流器控制的直流线路,形成交直流并联结构。进而比较交直流并联结构与传统方法治理台区的碳排放量差异,量化各环节的碳排放量,分析治理目标对交直流并联结构的约束。算例结果显示,基于交直流并联结构的台区支线对于线路电压偏差治理及减少功率损耗效果明显,且相较传统方法减少了碳排放量。引入交直流并联结构治理边远台区,对于台区因供电范围过长和负荷增加等引起的电压问题,提供了一种低碳的治理方法。In response to improve the power quality of remote stations,while reducing carbon emissions,it was proposed a transformation method for remote stations based on an AC/DC parallel structure.A voltage source converter,it was introduced to control the DC line,forming an AC DC parallel structure.Furthermore,compare the differences in carbon emissions between the AC/DC parallel structure and traditional methods for managing the substation area,quantify the carbon emissions of each link,and analyze the constraints of governance objectives on the AC/DC parallel structure.The calculation results show that the substation branch line based on the AC/DC parallel structure has a significant effect on controlling line voltage deviation and reducing power loss,and reduces carbon emissions compared to traditional methods.Introducing an AC/DC parallel structure to govern remote substation areas,a low-carbon governance method is thus provided for voltage issues caused by excessive power supply range and increased load in the substation area.
