  • 遠方系統の単相実効値模擬による電力系統瞬時値解析の高速化

    野田 琢 , 坂本 織江 , 米澤 力道

    … Electromagnetic transient (EMT) simulations of relatively-large power systems have become quite common, for instance, in the case where simulations of HVDC converters are carried out with large AC power systems connected to the converters. … To reduce computation time, this paper proposes a method to reduce computational demand of a remote power system which is located far from the source of a transient event to be simulated. …

  • 三相三アームハーフブリッジコンバータ : SCATによる回路開発

    森田 浩一

    従来の三相の力率改善回路付きコンバータは三相の昇圧回路の力率改善回路部分とDC/DCコンバータ部分の2ステージでコンバータが構成されていた。このため2回変換があるため全体の効率は掛け算で効いてきて全体の効率を上げることは難しかった。今回新しく提案する三相の力率改善回路はハーフブリッジに1アーム追加した形の三アームハーフブリッジとも言うべき回路で三つのメインスイッチと1個のトランスによって構成され、 …
