Disclosed are a tramcar power system and a method for controlling the system, the system comprising: a fuel cell (11) coupled to an unidirectional direct-current converter (14); a super capacitor (12) coupled to a first bi-directional direct-current converter (15); and a power battery (13) coupled to a second bi-directional direct-current converter (16), wherein the unidirectional direct-current converter (14), the first bi-directional direct-current converter (15) and the second bi-directional direct-current converter (16) are coupled to an inverter (18) via a direct-current bus (17); the inverter (18) is coupled to a motor of the tramcar; the fuel cell (11), the super capacitor (12), the power battery (13), the first bi-directional direct-current converter (15), the second bi-directional direct-current converter (16) and the inverter (18) are coupled to a master control unit (19); and the master control unit (19) is coupled to a controlling device of the tramcar. In the present disclosure, the super capacitor (12), the fuel cell (11) and the power battery (13) are cooperated to supply electrical energy, so that the disadvantages of insufficient energy of the super capacitor (12) and insufficient power of the power battery (13) are solved, and the disadvantage complementation between these energy storage components are achieved. Moreover, the fuel cell (11) and the power battery (13) are mutually redundant so as to realize emergency rescue when one of them is under fault condition.
