The invention discloses an emergency island coordination control method based on a railway energy router. Relates to the technical field of electrified railway traction power supply. On the basis of collected real-time operation data and fault state monitoring data of each port and traction side power supply arm circuit of the railway energy router, logic state updating is carried out on a-phase and b-phase power supply arm fault judgment signals, and the railway energy router is driven to execute three different emergency mode switching control in a matched mode according to the fault signals. According to the invention, a flexible network construction type emergency island coordination control scheme is provided for the railway energy router, and the method can adapt to a fault operation scene of a traction power supply system, and achieves the self-healing of the voltage and frequency of a contact network in a power-losing section under different fault types. And effective traction conditions of the train pantograph are recovered, ordered energy response among the alternating-current and direct-current ports is coordinated, and emergency self-walking of the train in the power-losing section is supported.
