Abstract

電力線通信(PLC)信号の注入抽出モードにはディファレンシャルモードとコモンモードの2種類があるため,伝搬モードはそれらの組合せの4通りある.従って,デュアルモード伝送PLC方式には,これらの4通りの伝搬モードの中から最も良いモードを選ぶ選択型と,2つの注入抽出モードを同時に使用する同時型がある.本稿では,家庭内DC給電および船内DC給電を想定した電力線路を構築し,選択型及び同時型のスループット特性を評価した.その結果,電力線線路の平衡度が良い時には同時型を使用すれば,スループットが従来方式より最大で1.9倍以上改善することを実験的に示している.また,平衡度が良くない線路では,同時型と選択型を使い分けることによって,従来方式と同等もしくはそれ以上のスループットが得られることを述べている.

As the injection and reception modes of power-line communication (PLC) signals, two modes of the differential and common can be used, so that there are four kinds of propagation modes. The proposing dual-mode transmission PLC system uses these propagation modes. In this paper, two types of the dual-mode system have been studied. One is called "selective type" that chooses the best propagation mode from four modes. Another type is "simultaneous" type, which utilizes the two injection and reception modes at the same time. To evaluate the proposing systems, two kinds of power distribution systems were constructed, which were assumed as a DC power system in house and ship, respectively. By using these DC power distribution systems, the throughput performance was measured. As a result, if the electrical balance of the power-line channels was good, the throughput of the simultaneous type achieved 1.9 times or more performance comparing to that of the conventional type. Moreover, even if the balance was not good, the obtained performance was equal to or more than that of the conventional type by using the proposing method which used both types properly.
