To provide a regeneration countermeasure device capable of reliably preventing absorption of unnecessary energy.SOLUTION: In a regeneration countermeasure system 1, a regeneration countermeasure device 10 comprises a regenerative power absorption unit 12 having a capacitor 12b and a reactor 12c, a switcher 13 which switches connection between an electric car track 30 and the regenerative power absorption unit 12 and connects the electric car track 30 and the regenerative power absorption unit 12 when in a closed state, a voltmeter 14 for measuring a voltage at a portion between the electric car track 30 and the switcher 13, and a control unit 16 which controls the switcher 13 so that the switcher 13 is placed in a closed state and the regenerative power absorption unit 12 absorbs regenerative power from an electric car 40 when a voltage measured by the voltmeter 14 while the switcher 13 is in an open state is larger than a prescribed voltage and a ripple satisfying a prescribed condition is not contained in the measured voltage.SELECTED DRAWING: Figure 1

    【課題】不要なエネルギーの吸収をより確実に防ぐことができる回生対策装置を提供する。【解決手段】回生対策システム1において、回生対策装置10は、コンデンサ12b及びリアクトル12cを有する回生電力吸収ユニット12と、電車線30と回生電力吸収ユニット12との接続を切り替えるものであり、閉状態のときに電車線30と回生電力吸収ユニット12とを接続する切替器13と、電車線30と切替器13との間の部分の電圧を測定する電圧計14と、切替器13が開状態のときに電圧計14で測定された電圧が所定の電圧より大きく且つ上記測定された電圧に所定の条件を満たすリプルが含まれていない場合に、切替器13が閉状態であり回生電力吸収ユニット12が電車40からの回生電力が吸収されるよう、切替器13を制御する制御部16とを備える。【選択図】図1
