After investigating the training methods of centralized control operation of many power generation enterprises, it is found that the three contents of on-site equipment, system diagram and procedure are relatively discrete from each other in traditional training, and employees often need to spend a lot of time and energy to initially combine the three contents and understand and learn. Based on WinForm and WeChat mini program platform, the thermal power centralized control operation training system is developed, combining traditional training methods with modern technology. Through software, the actual equipment, system drawings and procedures are combined to provide employees with more intuitive and visual learning methods, so that employees can understand and master knowledge more easily. Improve employee learning efficiency and learning experience.
