Summary:PROBLEM TO BE SOLVED: To provide an electric power system which, with respect to a conveyance facility comprising a vertical conveyance machine and plural horizontal conveyance machines, reduces a load on primary side electric power equipment and effectively uses regenerative electric power.SOLUTION: An electric power system comprises an electric power conversion device 20 which converts AC power from a primary side electric power source 70 into a direct current by a rectifier 21 and then converts the same again into an alternating current suited for raising and lowering a vertical conveyance machine 90, and a control device 50 controlling the electric power conversion device 20. To a DC intermediate circuit 22 of the electric power conversion device 20, a power storage device 35 is connected via an auxiliary electric power device 30, and a raising and lowering inverter 29 for driving an electric motor of the vertical conveyance machine 90 and plural traversing inverters 28 for driving respective electric motors of horizontal conveyance machines 80 are connected.SELECTED DRAWING: Figure 2 【課題】垂直搬送機及び複数の水平搬送機からなる搬送設備について、一次側電源設備の負荷を軽減し、回生電力を有効に利用する電源システムを提供する。【解決手段】一次側電源７０からの交流電力を整流器２１により直流に変換した後に垂直搬送機９０の昇降に適した交流に再び変換する電力変換装置２０と、電力変換装置２０を制御する制御装置５０を備え、電力変換装置２０の直流中間回路２２には、補助電源装置３０を介して蓄電装置３５が接続されるとともに、垂直搬送機９０の電動機を駆動するための昇降インバータ２９及び水平搬送機８０の各電動機を駆動するための複数の横行インバータ２８が接続されている。【選択図】図２
