Qingdao Zhengli: Leading a New Era of Intelligent Hydropower - In depth Report on the Chinese Brand Archives Column

Recently, Zhang Dachun, the executive director of the "Chinese Brand Archive" program, led a team to set foot in Qingdao, Qingzhou, Shandong Province, as well as Hunan Province and other places to carry out a series of filming activities.

This filming activity not only focuses on the important position of Qingdao Zhengli Electric Power Equipment Co., Ltd. in the industry, but also conducted in-depth interviews with key figures such as the company's general manager Pang Zijing and former director of Fengtan Hydropower Plant Yang Changxi. Since its establishment in Qingdao in 2006, Qingdao Zhengli Electric Power Equipment Co., Ltd. has been committed to innovation and technological development, leading the progress of the industry.

Sailing on a giant ship, exploring the field of intelligence
The automatic turning device developed by Qingdao Zhengli Electric Power Equipment Co., Ltd. drives the rotor through an elastic couple and is used to adjust the center of the rotating equipment shaft system.

This innovative device has obtained invention rights in multiple countries such as China, the European Community, the United States, and Canada, and has been successfully applied to the world's largest water conservancy projects, such as the Three Gorges Dam hydroelectric unit, as well as multiple hydropower stations such as Changheba, Nuozhadu, Pubugou, and Goupitan, achieving significant results. In addition, the innovation of the device has also earned it the Innovation Award at the China Patent Technology Expo and high recognition in the industry.

For many years, Qingdao Zhengli Electric Power Equipment Co., Ltd. has improved the efficiency of hydropower generation through continuous technological innovation, continuously improved hydropower technology and equipment, enriched the content of hydropower technology, and filled the technological gap in the industry.
Wise people walk together, welcoming a new era
Looking back at the 1990s, the Qingdao Zhengli Automatic Turning Gear Installation Project was launched for the first time. The first enterprise to dare to take this innovative step is now the Fengtan Hydroelectric Power Plant of State Grid Hunan Electric Power Co., Ltd. This action was not common among state-owned enterprises at that time. Yang Changxi, who was then an engineer at Fengtan Hydroelectric Power Plant, became a brave leader. Together with Pang Zijing, he led the cooperation between Fengtan Hydroelectric Power Plant and Qingdao Zhengli, marking a historic moment for the application of Qingdao Zhengli's automatic turning device nationwide.

This cooperation not only injects strong confidence into the technological innovation of private enterprises, but also demonstrates the local courage to explore, demonstrating the firm support and determination of local water conservancy and hydropower stations for local technological innovation.
The journey of transformation, the path of continuous innovation
During the filming process, the filming team specifically went to Fengtan Hydroelectric Power Plant of State Grid Hunan Electric Power Co., Ltd. to gain a deeper understanding of the practical application benefits of the automatic turning device. On the magnificent Fengtan Hydropower Plant Dam of the State Grid, the words "safety responsibility is more important than Mount Tai" are particularly striking. The automatic turning device developed by Qingdao Zhengli Electric Power Equipment Co., Ltd. has made significant contributions to the normal and efficient operation of hydropower plants by providing excellent performance, determining the direction of rotation, determining the swing direction, and fully meeting the requirements of adjustment processes.

For a long time, the automatic turning device has undergone multiple technological upgrades, from scratch to strength. Pang Zijing mentioned in an interview that after 31 years of development, the automatic turning device has been upgraded and renovated four times. Every advancement brings new technological breakthroughs, from couple drive to the introduction of elastic concepts, and then to automatic directional control, safe operation design, and the gradual improvement of device performance and stability. It continuously meets the needs of the industry, adapts to the rapid progress of intelligence level, and also promotes the development of the hydropower industry.

Smart deployment, with installations scattered throughout important water conservancy projects
Today, the automatic turning gear developed and produced by Qingdao Zhengli Electric Power Equipment Co., Ltd. has been widely used in important water conservancy projects in the Yangtze River, the Yellow River, Dadu River, Lancang River, Jinsha River, the Yarlung Zangbo River, Songhua River, Hongshui River, Yuanshui River, Yalu River and other basins, providing strong support for Myanmar, Cambodia, Guinea, Laos and other countries.

Spanning across multiple regions, witnessing the path of innovation in hydroelectric installations; Deeply explore and appreciate the leading position of Qingdao Zhengli; Exclusive interviews with individuals and genuine interviews with leaders of Qingdao Zhengli. The production team of the "Chinese Brand Archives" program has collected rich image materials and materials through this on-site shooting activity, and is currently fully investing in post production.

The audience will gain a deeper understanding of Qingdao Zhengli Electric Power Equipment Co., Ltd.'s outstanding contributions in the field of hydropower, as well as its active efforts in implementing intelligence and automation, through the documentary program "Chinese Brand Archives - Qingdao Zhengli Chapter". Through this high-level documentary, the audience will feel the struggle and pursuit of Chinese hydropower industry builders, documenting the magnificent picture of Qingdao Zhengli leading a new era of intelligent hydropower. Stay tuned for the exciting presentation of this documentary!
