摘要

本文对直流配电系统的能效问题进行了研究。建立了馈线和负载的效率计算模型，分析了AC/DC、DC/DC和DC/AC的效率。此外，还计算和比较了交流系统和两种直流系统(单极和双极)的能量效率。论证了采用直流供电系统比采用交流供电系统对办公楼的节能效果。分析表明，直流配电系统的能效高于交流配电系统。

Research on Energy Efficiency of DC Distribution System

Energy efficiency of DC distribution systems is researched in this paper. Efficiency calculation models of feeders and loads are established, efficiencies of AC/DC, DC/DC and DC/AC are analyzed. Moreover, energy efficiencies of an AC system and two DC systems, monopole and bipolar, are calculated and compared. The efficiency improvement of office building supplied by DC power system compared to supply by AC power system is demonstrated. From analysis, it is showed that the energy efficiency is higher in DC distribution system than AC distribution system.
