The determination and perseverance of dripping water and piercing stones can only be exchanged for innovative breakthroughs that gather sand and make towers. At present, digitalization and intellectualization have become the wind vane for the development of many industries. Han Tianqi, Sun Jian and Wu Tingji, young employees of the State Grid Yantai Power Supply Company, spontaneously set up the Rpa digital robot innovation and development studio, and broke a new path of business Digital transformation. Rpa is the abbreviation for Robotic Process Automation. It can be understood as a way for "virtual robots" to replace manual labor, also known as "digital employees". Rpa robots simulate human behavior and integrate existing intelligent automation technologies, replacing manual labor to complete periodic and repetitive tasks according to established rules. As an emerging programming language in recent years, its content brings both the tension of challenging unfamiliar skills and the excitement of exploring the unknown. Han Tianqi, Sun Jian, and Wu Tingji purchased online teaching courses and books at their own expense, starting from scratch to self pressurize. In the judgment of if conditions and cyclic applications, we must pay attention to the refresh conditions of this element. For the process quadrant evaluation method, we need to grasp the two dimensions of input-output ratio and process complexity. They set up study groups in their spare time, often discussing until early morning. Combining their professional knowledge in marketing, operation inspection, power supply station management, etc., they learn, discuss, and digest at the same time, starting from a small application and gradually practicing it into a wider field of expertise. At the same time, they have also expanded their learning of VB programming knowledge in Excel. After six months of hard study and research, the personnel of the Rpa digital robot development studio have made a qualitative leap in their knowledge reserves. They have accumulated three online courses and nine books, including "Black Horse Rpa Learning Management", "Rpa Code Programming", and "Uiperth Rpa Development". Han Tianqi was admitted as a senior development engineer at Rpa, while Sun Jian and Wu Tingji were admitted as intermediate development engineers. In practical applications, Han Tianqi, Sun Jian, and Wu Tingji went to the grassroots frontline to conduct demand research, and found that weak points such as high duplication of work and low efficiency were mainly concentrated in data integration and electricity cost analysis. In response, they utilized their break time to develop 21 automated business scenarios such as remote data collection and inspection. Through advanced digitization and automation technology, and the use of "digital employee" technology as a powerful solution, through flexible and rapid deployment, they brought significant benefits in a very short period of time. They also combine big data, AI and other technologies to form "super automation" tools, which are applied in professional fields such as power information and supply chain to help reduce burden at the grassroots level and achieve enterprise empowerment. In order to promote the promotion of Rpa technology in the Yantai power industry, the Rpa Digital Robot Innovation and Development Studio was opened to Yantai power supply employees in 2022. For students at different levels, four offline centralized training sessions were organized at three levels: basic introduction, skill advancement, and competition level improvement. A Yantai Power Rpa technology exchange group was established to continue skill teaching through online means, Answer various questions raised by companies during the development and deployment of Rpa applications, and assist power supply companies in various counties and cities to establish their own Coe (machine)
