In 2023, Tianjin Haoyuan Huineng completed the pilot project for the construction of a panoramic intelligent operation and inspection system for the largest water-based photovoltaic power station in China's Three Gorges project. The construction and design of the panoramic intelligent operation and inspection system aims to deeply implement the guiding ideology of "centralized monitoring, regional maintenance, unmanned, and few people on duty" for the booster station, apply new generation intelligent and information-based technologies, solve the pain points and difficulties of substation work, and liberate employees from heavy and repetitive tasks. Mechanical inspection is used instead of manual inspection, warning maintenance is used instead of sudden maintenance, and intelligent technology is used to reduce equipment failure rates, so that station personnel can truly feel at ease with "no one but few people".

In this pilot project, Tianjin Haoyuan Huineng utilizes multiple innovative technologies such as remote centralized control, intelligent perception, and intelligent decision-making to explore and attempt the application of remote intelligent inspection systems for substations, auxiliary equipment monitoring systems for substations, and rapid fault location systems for distribution networks in the operation and maintenance of photovoltaic power stations, improving their efficiency and stable operation. Fully utilize one's own advantages and experience, provide comprehensive solutions, including survey, design, construction, and other links, and achieve safe, efficient, and reliable construction goals.

Tianjin Haoyuan Huineng will closely cooperate with various partners to jointly promote the development of electric energy and strive to achieve the sustainable development goals of green and low-carbon. The construction of the panoramic intelligent operation and inspection system for the Three Gorges Photovoltaic Power Station in China will set a model for the overall solution of intelligent operation and inspection for new energy. At the same time, Haoyuan Huineng will strengthen technological research and innovation, improve the operation and maintenance efficiency and reliability of the photovoltaic power station, and make greater contributions to the development of the power energy industry.
