The operation and maintenance management of substation is one of the typical application scenarios of artificial intelligence in energy and power system. The artificial intelligence technology

mainly represented by expert system

traditional machine learning

and deep learning

is significant in promoting the development of substation intelligence. Firstly

we summarized the development status and characteristics

challenges

development trends and hot spots of artificial intelligence technology. Then

in combination with the advanced functional requirements of two major information systems in the substation

namely

the remote monitoring system based on sensors and the remote viewing system based on cameras

we analyzed the progress of artificial intelligence technology in typical scenarios such as assessment and diagnosis of major electrical equipment status

intelligent perception of substation security environment

and detection and discrimination of personnel behavior. Meanwhile

we pointed out the problems existing in the current application of artificial intelligence technology in the above-mentioned typical scenarios of substations. Finally

we put forward several suggestions on the key breakthrough areas in the future application of artificial intelligence technology to vital equipment state awareness and 3D panoramic visualization of substations.
