分散電源を含む直流ループ型配電システムの一構成とその制御法

抄録

In the large-scale factories, a lot of inverter loads exist, and these inverter loads are connected into ac system by using rectifiers to each inverter load. Moreover, DGs (Distributed Generators) or ESSs (Energy Storage Systems) which have dc outputs will be introduced to distribution system more and more, and these are connected into ac system by using inverters in conventional ac systems. Therefore, it is expected that the meaning to achieve dc distribution system which can reduce losses due to rectifiers and inverters, will be developed.
In this paper, dc loop type distribution system is proposed. Moreover configurations and simulation results of the inverter, the bi-directional rectifier, the PFC (Power Factor Corrector) and dc/dc converter which are used in this system are shown.
