The invention provides an electrified railway through power supply crossing power utilization system and a control method, and relates to the technical field of electrified railway power supply. The structure comprises a transformer substation, a three-phase high-voltage bus HB, a main traction substation CTS, a first traction substation STS1, an (n-1) th traction substation STSn-1, a traction network OCS and an optical fiber network FO, wherein the main traction substation CTS comprises a compensation transformer TCT, negative sequence compensation converters CO1 and CO2, a reactive compensation and energy management converter CO3, a matching transformer MT, an energy utilization and storage system EUSS and a measurement and control system MCS. The measurement and control system MCS detects the power of the traction substation group, carries out information interaction through the optical fiber network FO, controls the energy utilization and storage system to absorb and utilize the crossing power and the regeneration power in real time, carries out peak elimination and valley filling on the traction load, can compensate negative sequence and reactive power in real time, and improves the electric energy quality of the system.
