The invention discloses an energy storage cophase power supply system based on a V-connection traction transformer, a control method and a storage medium, and belongs to the technical field of electrified railway power supply. The energy storage in-phase power supply system comprises a V-connection traction transformer, three single-phase compensation devices, an energy storage device and a coordination control device. The primary side of the V-connection traction transformer is connected with a three-phase power supply, and any port of the secondary side is connected with a traction load; aC ends of the three single-phase compensation devices are respectively connected to different ports of the secondary side, and DC ends are connected in parallel to a DC bus; the energy storage device is also connected in parallel with the DC bus. The coordination control device collects current and voltage signals and controls operation of the devices. The system has the functions of energy storage and in-phase power supply, and solves the problems of large traction load fluctuation of a traditional electrified railway traction substation, power return caused by train regenerative braking, train over-electricity split-phase stall and electric energy quality management.

    本发明公开了一种基于V接牵引变压器的储能同相供电系统、控制方法及存储介质,属于电气化铁路供电技术领域。该储能同相供电系统包括V接牵引变压器、三个单相补偿装置、储能装置和协调控制装置。V接牵引变压器原边接三相电源,次边任意端口接入牵引负荷;三个单相补偿装置交流端分别接入次边不同端口,直流端并联接入直流母线;储能装置亦并联接入直流母线。协调控制装置采集各电流、电压信号,控制各装置运行。本发明具有储能和同相供电的功能,解决了传统电气化铁路牵引变电所牵引负荷波动性大、列车再生制动导致功率返送、列车过电分相失速、电能质量治理的难题。
