The total power plant may comprise a plurality of phases, which may be a form of power delivery, each phase may comprise alternating currents of the same frequency, the same amplitude and a difference in phase, which may be 120 °. Specifically, the plurality of phases may be an a phase, a B phase, and a C phase. The phases a, B and C may be three-phase power, and represent alternating current potentials having the same frequency, the same amplitude and phases which are sequentially different from each other by 120 °, and the corresponding phases may be identified using cables of different colors in the above-described total power equipment. The terminal 102 may acquire multiple sets of first power data of total power devices in the cell within a preset time. The preset time may be set according to actual conditions, and may be 15 minutes, for example, the plurality of sets of first power data acquired by the terminal 102 may be power data of the total power equipment in different phases, such as power data of an a phase, a B phase, and a C phase, that is, the terminal 102 may acquire power data of an a phase, a B phase, and a C phase of the total power equipment in the transformer area within 15 minutes.
