Large hydropower stations are generally designed according to the principle of "no one on duty, few people on duty", whereas, the remote display of production information depends on a inefficient reporting mode. To solve this problem, the equipment properties and management features of large hydropower stations are studied, and the real-time production display system based on Action Script and ASP.NET technologies is developed. By screening the production information, dynamic programming of pictures, data visualization and other means, the remote visual display effect of the complex equipment system is improved, which is available for reference in the development of similar production systems.
