摘　　要：针对目前分布式能源量小面多的特点,提出一种基于交直流同线输电技术的能源传输方式。通过分析交直流同线输电线路的原理,在满足现有的输电线路传输规则下,对叠加的直流电能的电压与电流进行分析与设计,并对交直流同线输电方式下的线路损耗与输送容量进行分析,得出交直流同线输电可以比现有的增容方式输送更大的容量。利用Matlab/Simulink搭建仿真模型,验证交直流增容方案的可行性。Aming at large scale of distribution sources, a new energy transmission way based on simultaneous AC-DC transmission was presented. By analyzing the principle of simultaneous AC-DC Transmission, under the rules of the existing transmission, voltage and current of superimposed DC power were designed. At the same time, the transmission line loss and capacity-increasing were analyzed, the obtained simultaneous AC-DC transmission can transport larger capacity than the existing capacity way. And simulation models were built by Matlab/Simulink to verity the feasibility of AC and DC capacity program.
