The invention provides a movable control power supply for a power plant or an intelligent transformer substation and a control method thereof, wherein the movable control power supply relates to the field of control technology for a power system. The control power supply comprises an AC input terminal, an AC switch, a monitoring module, a power supply module, an insulated monitoring device, an alarm device, a DC switch, a DC voltmeter, a DC ammeter, a current sensor, a voltage sensor and a DC output terminal. The monitoring module receives an instruction of an upper computer. A composite digital control mode in which fuzzy self-setting PI controlling and repeated controlling are combined is used for automatically adjusting input voltage. The control power supply outputs stable DC voltage. The insulated monitoring device automatically detects whether a DC output loop is grounded or insulation is complete. According to the movable control power supply, an integrated and modular structure is utilized; and functi
