An electric heating power control method comprises the steps that control periods are defined, and a plurality of comparison periods are defined in each control period; a plurality of control groups are arranged, and each control group comprises a plurality of heating loops on the satellite; setting a total power limit QU for each control group; the power Q, the temperature control threshold low temperature limit TL and the temperature control threshold high temperature limit TH of each heating loop in the control group are obtained; the on-off state of a heating loop in the control group and the current temperature T of a temperature-controlled object corresponding to the heating loop are obtained in real time; the high-temperature limit approaching rate K of the heating loop is calculated in real time; if n heating loops are switched on in the current control period and the power of the i-th switched-on heating loop is Qi, the power sum QT of the real-time switched-on heating loops is calculated; and comparing the QT with the QU, and performing power distribution. According to the method, the thermal control total power serves as a regulation and control target, the thermal control power is autonomously distributed, the working state of an electric heating loop is planned as a whole, the electric heating power in the autonomous thermal control process is compressed, and the power consumption of a whole satellite platform is reduced.
