In view of the problems exiting in grounding line management system

this paper proposes a new generation temporary grounding line management system which is composed only of the grounding line management machine and a wireless locking device. This new generation system is designed to monitor and control the location status of the temporary grounding line

high-voltage net door

GIS door and manual switch device in the normal or smart substation. The advantages of the new generation temporary grounding line management system are summarized and compared with those of other systems. Furthermore

comments are made on the hardware structure of the grounding line management machine and the wireless locking device

the flow design of the software

the security analysis of wireless communication

the solutions of critical questions of the wireless locking device design. This method has been successfully applied to the temporary grounding line management system in a 220 kV smart substation and the dispatch and control of power systems

which has markedly improved the operating security and station automation level.
