en.Wedoany.com Reported - On March 31st, the generator stator hoisting operation for the world's highest altitude and Tibet's first tower Concentrated Solar Power (CSP) project—the Tibet Kaitou Tushuo 100MW Molten Salt Tower CSP Power Generation Project—was successfully positioned with the coordinated efforts of all construction personnel. This marks a key breakthrough in the installation of the project's core equipment, laying a solid foundation for subsequent unit installation, commissioning, and grid connection.
The generator stator is the core load-bearing component of a CSP power generation unit. The precision of the hoisting work directly affects the subsequent operational safety and stability of the unit. The stator to be hoisted measured 6.55 meters in length, 3.6 meters in width, 3.64 meters in height, and weighed approximately 135 tons. Hoisting such a massive object with millimeter-level precision into a narrow foundation slot in the main plant building on the northern Tibetan plateau, at an altitude of 4700 meters with frequent strong winds, presented considerable difficulty. The process faced multiple risks including swaying from high-altitude wind disturbances, imbalance in equipment load, performance degradation of machinery due to low temperatures, susceptibility to bumps and misalignment in confined spaces, and uneven stress due to foundation settlement, leaving extremely low tolerance for error in precision control.
To ensure safe and efficient operation, a specialized task force was established during the project's preliminary stage. They formulated a detailed hoisting plan based on site conditions and stator parameters, optimizing equipment selection and rigging combinations. Prior to the operation, technicians conducted comprehensive inspections and debugging of the hoisting equipment, and provided safety and technical briefings to the operating personnel. During the hoisting process, commanders coordinated precisely, operators strictly followed the plan, smoothly completing the lifting, lateral movement, and alignment of the stator. High-precision equipment monitored posture and displacement throughout the entire process, ensuring accurate placement and a hazard-free hoisting operation.
The successful hoisting and positioning of this generator stator marks the commencement of construction for the steam turbine generator set of the Tibet Amdo CSP project. In the next step, the project team will accelerate the alignment, fixation, and subsequent supporting installation of the stator, strictly controlling quality and safety to drive the project forward on schedule, contributing to the construction of the clean energy base in northern Tibet.
According to previous reports, as a key energy project in Tibet's 14th Five-Year Plan, the CSP component of the Tibet Amdo Tushuo 100MW CSP + 800MW integrated project is located in the Tanggula high mountain area at an altitude of 4645 to 4657 meters. Its construction faced numerous world-class challenges, setting a new world record for the altitude of CSP projects. The project is invested in and constructed by Tibet Development and Investment Group Co., Ltd., with a consortium of PowerChina Northwest Engineering Corporation Limited and Shandong Electric Power Construction No.1 Engineering Co., Ltd. serving as the general contractor. It utilizes key power system equipment such as the concentrating solar collector system, steam generator, and steam turbine generator set from Dongfang Electric Corporation Dongfang Boiler Co., Ltd.
