For the problem of the regenerative braking energy in the rail transit, some research on a kind of magnetically suspended flywheel array-based energy recovery system is done. Through analysis on the structure of the traction power supply system, the braking methods and energy consumption during the rail pulling in are introduced. And then the contrast results of the energy consumption are provided before and after adding the energy-storaged equipment. Based on this, a kind of the flywheel energy-storaged array-based DC power recycling system is designed which can be used to achieve a fast braking power absorption during pulling in and power compensation during pulling out of the rail train. With the argumentation of the flywheel key performance indices, the parallel strategy and the capacity assignment are demonstrated. Finally, the experimental platform of the flywheel energystoraged array is developed with the real test system. The mutual-driven charging and discharging results can be able to demonstrate the effectiveness of the designed.
