Digital substation technology is a modern substation technology that establishes the basis of IEC61850 communication standard. It involves intelligent primary equipment, networked secondary equipment and automated operation management system. Digital substation technology has been successfully applied to domestic power system. The main key technologies of digital substation are introduced. By analyzing the characteristics and problems of urban rail transit power supply ring network, it is proposed that GOOSE communication networking technology be applied to urban rail transit power supply ring network, which enhances the selectivity of ring network relay protection And quick speed.
