Description

technical field [0001] The invention belongs to the technical field of smart grids, and in particular relates to an intelligent operation inspection system and method for power transmission equipment. Background technique [0002] With the development of modern society, the electricity consumption of the whole society is increasing year by year. To meet the ever-increasing demand for electricity, the power system, including power plants, substations, and transmission stations, continues to grow in size. The increasingly complex power system has become a challenge to maintain high grid stability. In order to avoid the serious impact of transmission system failure on industrial production and people's life, the fast, intelligent and accurate operation and maintenance and fault detection of power grid equipment are of great significance to ensure the safety and stability of social power supply. [0003] As of the end of 2019, the length of China's existing 35 kV and above tra...

Problems solved by technology

The former senses the operating status of the power grid based on electronic sensors, and transmits back through Zigbee, Wi-Fi or other wireless communication technologies, but there are problems of high cost, high power consumption, and small coverage; the latter uses robots or drones for automatic monitoring. Patrol inspection requires pre-acquisition of three-dimensional data modeling of the power grid, which has problems such as high operating costs and poor ability to resist environmental electromagnetic interference
