The invention discloses an electrified railway traction power supply capability boundary evaluation method. The method comprises a parameter input module; an electrical modeling module; the load flow calculation module is used for calculating the traction network load flow of the vehicle-network electrical interactive coupling system in consideration of load network voltage iterative calculation under various operation conditions; and the power supply evaluation module is used for solving the electrical quantity of power supply equipment based on a non-planar graph load flow calculation result, comparing and analyzing a theoretical calculation result and a national standard specified value, and uniformly reducing the line transportation capacities under different driving organizations to form a system maximum power supply capacity boundary evaluation system with the line maximum transportation capacity as a representation. The power supply capability evaluation time domain is wider, the evaluation process is more convenient, and the precision is higher. The method is wider in power supply capability evaluation time domain, more convenient in evaluation process and higher in precision, and is suitable for power supply capability evaluation of lines such as existing non-plain map driving organizations, combined transportation of multiple different types of electric locomotive groups, large and small intersection line planning and the like.
