The invention discloses a partition power supply system for managing a stray current at a railway vehicle depot and a control method. The partition power supply system and the control method are used for managing the stray current at the vehicle depot and ensure that vehicles can normally exit and enter the vehicle depot. The system comprises insulation joints J (comprising J1 and J2 ), contact line sections D (comprising D1 and D2 ), high-powered direct current thyristor switches A (comprising A1, A2, A3 and A4), track axle counters B (comprising B1, B2, B3 and B4 ), and a state identification control unit (C), wherein the two insulation joints (J1 and J2 ) are arranged between the vehicle depot and a main line, and the spacing is longer than 1.5 times of the length of the vehicle, the high-powered direct current thyristor switches (A1 and A2) are respectively connected with two ends of the first insulation joint J1 and the second insulation joint J2; the two track axle counters are respectively mounted beside tracks on two sides of the first insulation joint J1; the two track axle counters are respectively mounted beside tracks on two sides of the second insulation joint J2; output signals of the four track axle counters and the running state signals of the power supply system are connected with the state identification control unit; the state identification control unit controls the ordered switching on and the switching off of the four high-powered direct current thyristor switches in an output manner.
