The invention relates to a rapid starting method of a DC power distribution system. The method comprises the following steps: starting a control system; starting a constant DC voltage converter station; starting a constant active power converter station; judging whether there is an energy storage device or not; if there is an energy storage device, accessing the energy storage device and then accessing a distributed power supply; and if there is no energy storage device, directly accessing the distributed power supply and then accessing a load to finish starting. The starting steps of the DC system and the starting requirements of the converter stations and a DC transformer are specified, and the problem that the DC power distribution system is started slowly is solved.
