Protection technology of coal mine power based on GOOSE network with information sharing

YAO Fuqiang;BAI Meng;ZOU Wenbing;Department of Electrical Engineering and Information Technology, Shandong University of Science and Technology;  
For problems of override trip in short-circuit fault and fault line selection in single-phase earth fault of coal mine power system, a protection technology of coal mine power based on GOOSE network with information sharing was proposed. The technology realizes anti-override trip with blocking signal and line selection in singlephase earth protection with zero sequence full current vector information based on GOOSE network. On the basis of existing gigabit industrial Ethernet of coal mine and high-speed real-time communication mechanism of GOOSE,fault information can be shared between protection devices, which can realize anti-override trip effectively and improve accuracy of fault line selection in single-phase earth fault.
