Along with the power construction and the introduction of the power market competition mechanism in China, the application prospects of artificial intelligence in power system will be broader. The problem of power system safety management suit able for artificial intelligence application is analyzed, and several -widely used artificial intelligence technologies are introduced. The development trend and application prospect of artificial intelligence in power system are pointed out finally. Team is the smallest unit of an enterprise, and strengthening team safety management is an important guarantee for production. Taking the substation teams as an example, the application of artificial intelligence in improving the safety management of the teams is explored to provide basis for the construction of ubiquitous power Internet of thing for safety production by analyzing the main problems in the current safety management of the teams.
