PROBLEM TO BE SOLVED: To provide an electric power distribution system of a mobile which operates the power system of the mobile device with one generator.SOLUTION: A mobile power distribution system 100 includes: a first electric power system (8a) connected to a generator 5 and a first electric power load 7a whose power variation amount is less than a predetermined value; a second electric power system (8b) connected to a second power load 7b at which the amount of variation can be equal to or greater than a predetermined value; a first power converter 11; a second power converter 12; a third power converter 13; and a bus tie breaker 4. The bus tie breaker 4 is brought into a connected state when the second electric power load 7b is not in operation while it is brought into a shutoff state when the second electric power load 7b is in operation, the first power converter 11 is controlled based on a first power command value given by a low frequency component less than a predetermined frequency among power actual values of the second power converter 12, and the second power converter 12 is droop controlled. The third power converter 13 is controlled in power so as to eliminate an imbalance of the power flowing in and out from a DC intermediate portion 9.SELECTED DRAWING: Figure 1

    【課題】移動体の電力系統を発電機1台で運用する。【解決手段】移動体の配電システム100は、発電機5、及び、電力の変動量が所定値未満の第1電力負荷7a、に接続される第1電力系統(8a)と、変動量が所定値以上となり得る第2電力負荷7bに接続される第2電力系統(8b)と、第1電力変換器11と、第2電力変換器12と、第3電力変換器13と、バスタイブレーカ4と、を備える。バスタイブレーカ4は、第2電力負荷7bが運転していないときには接続状態とされる一方、第2電力負荷7bが運転しているときには遮断状態とされ、第1電力変換器11は、第2電力変換器12の電力実績値のうち所定周波数未満の低周波数成分で与えられる第1電力指令値に基づいて制御され、第2電力変換器12はドループ制御される。第3電力変換器13は直流中間部9に流出入する電力の不平衡を解消するよう電力を制御される。【選択図】図1
