Recently, the flywheel energy storage device independently developed by Xiangdian Power Co., Ltd., a subsidiary of Xiangdian Co., Ltd., successfully completed a smooth trial operation at Guokai Avenue Station of Nanning Rail Transit Line 5.

as a backbone enterprise in China's electrical industry and a domestic research base for major national technical equipment, Xiangdian co., ltd. relies on the core advantages of "electromagnetic energy motor electric control" to transform the precise control technology of flywheel speed into an efficient two-way conversion scheme of "electric energy-kinetic energy", successfully solving the problem of electric energy loss caused by frequent braking of urban subway trains and realizing the recovery and reuse of braking energy. During the trial operation, the system runs stably and reliably, and the average daily power saving of a single machine is as high as 1600 kW, which is highly recognized by customers.

At present, Xiangdian has built a multi-scenario energy storage technology system. Its 10MJ, 15MJ, 40MJ and other types of flywheel energy storage devices, with their core advantages of high charge and discharge frequency, fast response speed, high power density and high discharge efficiency, not only perform well in the field of rail transit, but also are more widely adapted to multiple scenarios such as power grid frequency modulation, renewable energy consumption, UPS power supply guarantee, etc.

Since the beginning of this year, Xiangdian's flywheel energy storage project has successively carried out pilot applications in the subway systems of Qingdao, Hangzhou, Guangzhou, Nanning and other cities, in order to promote the urban rail transit system to be safe, efficient, and low-carbon., Intelligent development has injected innovative power.
