In July 2021, I interned at the Changsha branch of CalTec Intelligent Technology Co., Ltd. in Shenzhen. During this internship, I gained in-depth knowledge of the entire process of PCB development, from circuit design to component layout, and from routing the connections to planning ground lines and power tracks. I gradually mastered every critical step of the entire process. Additionally, I learned how to use circuit design software such as Altium Designer. By designing circuit diagrams based on actual requirements, I became familiar with component selection, layout, and connections. I even participated in the soldering process, which deepened my understanding of circuit construction and practical applications.

In July 2022, I interned at an intelligent power station. During my internship at the distribution substation, I received excellent guidance and training. I gained a deeper understanding of various equipment in power stations, such as transformers, isolating switches, and current transformers. I learned about the installation, commissioning, correct installation, and connection of power equipment. I also observed and learned about the monitoring and maintenance work of power systems. I gained hands-on experience in using professional tools to detect and troubleshoot equipment faults and perform routine maintenance. Overall, I acquired essential skills and knowledge for maintaining distribution systems. During the internship, I actively learned relevant professional knowledge and skills, exchanged ideas with the station’s engineers, and engaged in in-depth discussions. This internship not only familiarized me with the working environment and operating procedures of distribution substations but also deepened my understanding and interest in electrical engineering and its automation field.

In addition to my internship experiences, I actively participated in student organizations on campus. I served as a staff member of the Student Union in my college and organized events such as the University Sports Games and the civilized dormitory evaluation. I also participated in volunteer activities, such as volunteering for the “Zhaoyi Innovation Cup” competition. These experiences have enhanced my organizational and coordination skills, teamwork spirit, and sense of responsibility. They will help me engage in laboratory collaborations, project management, and interactions with classmates and professors during my master’s studies, promoting my comprehensive development in the field of electrical engineering.

As a student of electrical engineering and its automation, I have a solid academic foundation and extensive professional knowledge. I have grasped the core theories and practical applications of electrical engineering and its automation. After graduation, I am eager to immerse myself in the industry of control, delve into the relevant knowledge of electrical engineering and its automation, and pursue frontier technologies and innovative applications. I aspire to constantly improve my professional competence and contribute to the development of the field. I aim to cultivate research capabilities and innovative thinking, providing strong technical support to solve real-world problems. I have great admiration for your esteemed university’s distinguished faculty, advanced facilities, and beautiful environment. The university enjoys a prominent reputation both domestically and internationally and has nurtured numerous elites in the field of electrical engineering and its automation. Its academic atmosphere and research resources will provide me with abundant support and opportunities. I hope to study and research together with professors, continuously enhance my professional competence and research abilities.
