The invention discloses a high-speed magnetic levitation regenerative braking energy storage system, and the system comprises a braking resistor sharing a direct current bus, a super capacitor, a traction load and a power frequency power grid. The super capacitor is connected to the direct current bus through a bidirectional DC/DC converter, the traction load is connected to the direct current bus through a DC/AC converter, and the power frequency power grid is connected to the direct current bus through an AC/DC converter. The power distribution and current transformation requirements of the maglev train can be met, train braking energy recovery can be achieved, and the heat dissipation problem caused by the fact that electric energy is completely consumed by resistors is avoided.
