| Abstract: | A 1 MW flywheel energy storage array system is proposed according to the operation characteristics and train parameters of urban rail transit to absorb the braking power generated when the train is braking. By comparing different types of regenerative braking energy recovery methods, the necessity of application of flywheel energy storage system in urban rail transit are analyzed. The 1MW array flywheel energy storage system is carried out from the array optimization, security calculation and project implement anticipation based on the test data for the rail transit electrical drive line. The feasibility of 1 MW flywheel energy storage array system applied in urban rail transit is verified. |
