Abstract

The invention provides a distribution cable intelligent monitoring, early warning and first-aid repair guiding system based on the Internet of Things, and belongs to the field of safe and stable operation of a power grid. According to the invention, real-time information is sensed through various sensors at monitoring points; an analog signal is converted into a digital signal, information is processed through edge calculation, data is analyzed, compared and predicted through the intelligent operation and maintenance management and control platform, all-weather real-time monitoring of the urban cable operation condition is achieved, and abnormal alarm, emergency command, fault diagnosis and first-aid repair guidance of the urban cable are completed through comparative analysis of the data.Geographic information of the cable in the GIS and operation parameters of the cable are combined to complete rapid fault positioning, and power failure time is reduced. The problem that undergroundcable monitoring is difficult is solved, managers are helped to give an early warning in time and remove faults through real-time monitoring of the cable operation condition, and a guarantee is provided for safe operation of a power grid.

Description

technical field [0001] The invention belongs to the field of stable and safe operation of electric power systems, and relates to operation status monitoring, fault warning and emergency repair guidance of power distribution cables. Background technique [0002] With the increasing scale of the power grid and the increasing level of information technology, distribution cables have become the main force of urban cables, and the reliability of their operation directly affects the safety and stability of the power system. Excessive cable current will cause the line to heat up. Long-term heating of the cable will cause aging of the cable insulation, and even breakdown will cause a fire. Excessive humidity in the underground cable will also affect the safe operation of the cable. Real-time monitoring of the temperature and humidity of the cable is required. Partial discharge and temperature changes can reflect the insulation of the cable, and real-time monitoring of the insulation...
