Abstract: In recent years, building a digital power supply station is one of the important measures for the State Grid to promote the digital transformation. Promoting the digital transformation of power supply stations plays an important role in improving power supply reliability, reducing operation and maintenance costs, and reducing work burden. This paper systematically summarizes the construction background, connotation and application scenarios of digital power supply stations, and uses robotic process automation（RPA） technology to realize process automation, which helps grassroots power supply stations to reduce burden, improve quality and efficiency. Meanwhile, it also reveals the huge potential and advantages of digital technology in power supply station management and enhancing the core competitiveness of power enterprises.
