Abstract
Description
Technical Field

[0002] As an important infrastructure of the national economy, the safe and stable operation of the power system is crucial for national development. With the continuous expansion of the scale and the increase in complexity of the power system, higher requirements are put forward for the professional skills of power system operation and maintenance personnel. The traditional power system training methods mainly rely on theoretical learning and on-site internships, but there are problems such as low training efficiency, high cost, and high safety risks.
[0003] In recent years, power system simulation training technology has developed rapidly, mainly including two methods: pure software simulation and pure hardware simulation. The pure software simulation technology simulates the operation of the power system through a computer, with low cost and easy operation, but lacks a sense of reality and cannot simulate the actual operation environment, making it difficult for trainees to obtain real operation experience. The pure hardware simulation technology conducts training by simulating actual equipment, with a strong sense of reality, but high cost, difficult to simulate complex power system operation conditions, and poor flexibility.
[0004] In addition, most of the existing power system simulation training systems adopt a single technical solution and cannot effectively combine virtual devices and actual devices, resulting in limited training effects. For example, pure software simulation systems lack real operation experience, making it difficult for trainees to master actual operation skills; pure hardware simulation systems have high costs and poor flexibility, making it difficult to meet diverse training needs. In addition, the existing power system simulation training systems often lack an effective data interaction module, resulting in the inability to achieve real-time linkage between virtual devices and actual devices, and making it difficult to simulate complex power system operation conditions.
[0005] Therefore, developing a power simulation training system that combines virtual and physical devices, which can not only provide a real operation experience, but also flexibly simulate various power system operation conditions and achieve real-time linkage between virtual devices and actual devices, is of great significance for improving the professional skills of power system operation and maintenance personnel.
