Abstract

For the increasing power requirements of the more electric aircraft power system, the power distribution technology of the aircraft's high-voltage DC power supply system based on improved droop control is studied in this paper. By analyzing the existing problems of traditional droop control strategy, an improved droop control method with adaptive droop coefficient and output voltage compensation for the multi-source DC power supply system of more electric aircraft is proposed. According to the unbalance degree among the output power from different power supply units and the deviation between the actual output voltage and the initial output voltage, the droop coefficient of the traditional droop control and the output voltage command value are compensated. Therefore, the accurate distribution of output power and the stability of bus voltage are realized. The effectiveness and feasibility of this method are verified by simulation results.
