摘要
作为智能电网环境下的一种新型输电方式,交直流同线输电具有诸多优势.通过理论分析,推导其线路损耗特性,如有功功率损耗、无功功率损耗和线路电压降,并搭建仿真模型进行验证.仿真结果表明:当线路叠加的直流功率满足一定的传输条件时,交直流同线传输方式的线路损耗小于传统交流输电方式的线路损耗.
As a new way of smart grid, the principle of simultaneous AC-DC power transmission is analyzed, such as transmission line loss characteristics, line active power, line reactive power, line voltage drop. Then theoretical derivation for them has been carried on. The simulation results show that line loss of simultaneous AC-DC power transmission is less than line loss of the traditional AC power transmission way, when the superposition of line meet certain transport condition.
