POWER SUPPLY SYSTEM, POWER SUPPLY MANAGEMENT DEVICE, AND POWER SUPPLY

To provide a power supply system that can control power in accordance with the dynamic characteristics of a power source.SOLUTION: A power supply system comprises multiple power supplies connected to each other in parallel, from which power is supplied to a load. Each of the multiple power supplies comprises a power source and a power supply circuit. The power supply circuit 500 comprises: a drooping characteristic calculation unit 210 for calculating a voltage command value so that an output voltage should droop with respect to an output power outputted by the power supply at a prescribed droop rate; and a ramp rate control unit 510 for correcting the voltage command value so that the amount of change of the output voltage should be suppressed when the amount of change per unit time of the output power surpasses a prescribed ramp rate. The ramp rate is differently set according to the type of a power source for each of the power supplies.SELECTED DRAWING: Figure 11 【課題】電力源の動特性に合わせて、電力制御可能な電源システムを提供する。【解決手段】並列に接続される複数の電源から負荷に電力を供給する電源システムにおいて、複数の電源は、それぞれ電力源と電源回路とを備え、電源回路５００は、電源が出力する出力電力に対して出力電圧が所定の垂下率で垂下するよう電圧指令値を計算する垂下特性計算部２１０と、出力電力の単位時間あたりの変化量が所定のランプ率を超える場合には、出力電圧の変化量を抑制するよう電圧指令値を補正するランプ率制御部５１０とを備え、電源ごとに、電力源の種類に応じて異なるランプ率が設定される。【選択図】図１１
