Abstract: The growth of power demand makes various power companies devote themselves to the optimization and improvement of the distribution system, but the design of part of the distribution system is restricted by technical conditions, which makes the hierarchical management of the distribution system chaotic and automated. It is difficult to achieve the expected construction effect. With the gradual progress of information technology, power distribution automation technology has developed to a certain extent. The emergence of this technology also brings new possibilities to the design of power distribution systems. All power companies must pay attention to power distribution in the power distribution system. Application of automation technology. Based on this, this article will focus on the application of distribution automation technology in the distribution system, which is conducive to comprehensively improving the level of power services.
