The invention provides an ADPSS-based distributed power flow controller modeling and simulation method. Electromagnetic transient simulation of a distributed power flow controller on a power system digital simulation system ADPSS platform can be realized. The method comprises the steps that a double-loop power transmission system simulation model is established under the ADPSS/ETSDAC simulation environment, a DPFC device is appropriately simplified by using the UDM function module of the ADPSS/ETSDAC, a series side current converter equivalent mathematical model is established by using an equivalent voltage source, and a parallel side current converter equivalent mathematical model is established by using an MMC mean value model. The dynamic and static characteristics of the DPFC device and the regulation and control function for the system power flow can be reflected under the premise of guaranteeing the simulation scale so that the simulation accuracy can be guaranteed and the simulation time can be shortened; and the more reliable, more comprehensive and more detailed theoretical support can be provided for actual power grid safe and stable operation of the DPFC device, and the foundation can be laid for popularization and application of the distributed power flow controller.
