PROBLEM TO BE SOLVED: To realize reduction of power loss and harmonic waves, in a power distribution system of an electric propulsion ship including a multiplex rectifier having a number of converted phases exceeding 12.SOLUTION: A power distribution system includes n sets of distribution board bus bars connected annularly or radially by coupling lines, a generator for feeding power to at least 1 set of the n sets of distribution board bus bars, a multiplex rectifier connected with the respective n sets of distribution board bus bars by wires, and performing multiplex rectification of three-phase AC voltages supplied from the n sets of distribution board bus bars in parallel, and a phase-shifting transformer performing phase shift between the distribution board bus bars, so that each phase of the n sets of distribution board bus bar voltages is shifted by 60/n° (n is an integer of 3 or more).SELECTED DRAWING: Figure 1 【課題】１２パルスを超える変換相数の多重整流器を備える電気推進船の配電システムにおいて、電力ロスの削減と高調波の低減とを実現する【解決手段】配電システムは、結合線によって環状又は放射状に接続されたｎ組の配電盤母線と、ｎ組の配電盤母線の少なくとも１組に給電する発電機と、ｎ組の配電盤母線の各々と電線で接続され、ｎ組の配電盤母線から並列に供給された三相交流を多重整流する多重整流器と、ｎ組の配電盤母線電圧の位相が６０／ｎ°ずつシフトするように配電盤母線同士の間を移相させる移相変圧器とを、備える（但し、ｎは３以上の整数である）。【選択図】図１
