In tourist attractions of remote areas, overload operation and fire hazard often appears in power distribution equipment. In order to solve this problem, a security pre-warning system of low voltage distribution power users based on geographical information system is designed in this paper. The protection controller is developed in this system, which can real-time acquire electric parameters, switching value and temperature data of each low voltage distributed power user. The geographic position and corresponding data of distributed power users are displayed in this system. The electric power safety and fire hazard warning function can be realized by intelligent analysis. The system can well adapt to the complex features of low-voltage distribution equipment in tourist areas, and the visual management and information level of low voltage distribution network can be developed.
