Abstract: With the development of science and technology, intelligent technology based on the development of information technology has been widely used. For the rapid development of electrical engineering in our country, it has made a necessary contribution to the development of industrial modernization. The application of intelligence in automation control improves the automation control level of equipment operation, thereby promoting the reliable operation of electrical engineering systems. Based on this, this paper analyzes intelligent and automatic control, discusses the application in automatic control, and based on the application advantages of technology, through the effective combination of automation and intelligent technology, the allocation efficiency of resources is improved, and the power system is improved. The operation efficiency of the power system has promoted the comprehensive development of the industrial structure of the power system.
