Zusammenfassung:	To provide a power supply system capable of suppressing generation of resonance due to a higher harmonic wave from a power system, and a control device.SOLUTION: A power supply system of one embodiment includes a plurality of power conversion devices, a plurality of circuit breakers and a control part. The plurality of circuit breakers is individually connected to the plurality of power conversion devices and performs switching of electrical connection of the power conversion devices and a power system by switching between an on-state and an off-state. The control part controls the circuit breakers, switches connection states of the plurality of power conversion devices, and determines whether or not the power conversion devices in conduction states with the power system by the circuit breakers connected thereto being in the on-state and being in a stand-by state become a predetermined number of devices.SELECTED DRAWING: Figure 1 【課題】電力系統からの高調波による共振が発生することを抑制することができる電源システム及び制御装置を提供すること。【解決手段】実施形態の電源システムは、複数の電力変換装置と、複数の遮断器と、制御部とを持つ。複数の遮断器は、前記複数の電力変換装置にそれぞれ接続され、オン状態とオフ状態を切り替えることにより前記電力変換装置と電力系統との電気的な接続の切り替えを行う。制御部は、前記遮断器を制御して、前記複数の電力変換装置の接続状態を切り替えると共に、接続された前記遮断器がオン状態であることによって前記電力系統と導通している状態であり、且つ待機状態の前記電力変換装置が所定の台数となるか否かを判定する。【選択図】図１
