en.Wedoany.com Reported - The main structure of the inertia flywheel plant for the Xinjiang Huadian Mulei Kaisheng Flywheel Energy Storage Demonstration Project successfully topped out on June 2. Located in Mulei County, Changji Prefecture, the project is supplied with a full set of flywheel energy storage core equipment by Qingyuan Feikong, marking the official transition into the equipment installation and commissioning preparation phase.

This energy storage project is the core supporting facility for the Kaisheng Mulei 40 Wells 800MW Wind Power Project, with a total energy storage capacity of 31MW, located east of the 220kV collection station. Qingyuan Feikong customized 18 sets of 1.5MW high-speed flywheel energy storage units and one set of 5MW magnetic levitation inertia flywheel unit for the project. These are connected in a two-line "hand-in-hand" series configuration to the 35kV backup intervals of the T1 and T2 main transformers at the collection station, enabling efficient coordination with the wind power base.

This project also serves as the demonstration implementation of Topic 5, "10MW-Class Magnetic Levitation Flywheel Energy Storage Key Technologies," under the National Key R&D Program during the 14th Five-Year Plan period. Qingyuan Feikong participated in the technological breakthroughs of this topic. The supplied 5MW magnetic levitation inertia flywheel and high-speed flywheel array represent a critical step in transitioning the research outcomes from the laboratory to engineering applications. Featuring millisecond-level response, long lifespan, and high safety, they provide inertia support and fast frequency regulation services for new energy stations. Located in the Mulei Gobi, the project faces extreme environments such as strong winds, sandstorms, and large diurnal temperature variations. Qingyuan Feikong reinforced the design in areas including flywheel rotor materials, magnetic bearing systems, heat dissipation, and protection, and coordinated in advance with participating construction units such as CSCEC Zhonghuan on foundation embedding, installation procedures, and hoisting plans to ensure precise matching between civil works and equipment interfaces. With the topping out of the main inertia flywheel plant, the civil framework of the core area has been fully formed. The complete set of flywheel energy storage equipment supplied by Qingyuan Feikong will be delivered to the site in batches as planned. Subsequently, Qingyuan Feikong will station a technical team in Mulei to collaborate with all participating units on installation and commissioning, supporting the construction of the flywheel energy storage demonstration project.
