Everyone held the army to be the most beautiful country

Flywheel energy storage project real picture

　 This result creatively puts forward the coordinated control method of frequency modulation combined with traditional thermal power and new flywheel technology，It fills the gaps of 10-ton heavy duty rotor, 5-DOF radial ultra-low power permanent magnet offset hybrid magnetic bearing and its control technology and self-damped axial permanent magnet passive intrinsic stability support technology，The design, analysis and cooling problems of flywheel energy storage system high speed and high power integrated solid rotor hybrid excitation motor are overcome，Reach the international leading level。

　 The results were applied to the 2x600 MW cogeneration unit of Ningxia Lingwu Company, a national energy group, and 22 MW /4 were built with it as the core key technology.5 MWH maglev flywheel energy storage system with the largest capacity in the world。目前，All 12 flywheels have been completed and put into trial operation，It can effectively reduce the equipment wear problem caused by frequent operation of mechanical equipment，Reduce the load fluctuation frequency of the unit，The parameters of the unit are easier to control，Steam quality, coal consumption level, environmental protection parameters are more excellent，Further improve the safety and economy of the unit。

　 Huachi Power (Beijing) Technology Co., Ltd. is headquartered in Beijing, has raised hundreds of millions of yuan, is a national high-tech enterprise, Beijing special fine special new enterprise, Zhongguancun gold seed enterprise, Zhongguancun high-tech enterprise。The founder and core technology has won the first prize of national technological invention, 58 patents around the main business, and the core technology and products have complete independent intellectual property rights。Tongling Base of Anhui R & D and manufacture five degrees of freedom full magnetic levitation bearing and its control system as the core of power class magnetic levitation energy storage flywheel, high-speed magnetic levitation motor, satellite attitude control flywheel and other products, with an annual output of 1000 sets of flywheel products。

　 华驰动能公司五自由度电力级磁悬浮储能飞轮产品包括: 4MW/1000kWh/15分钟、500kW/1000kWh/2小时、500kW/125kWh/15分钟、600kW/125kWh/12分钟、500kW/50kWh/6分钟、500kW/8kWh/58秒、500kW/7.5kWh/54 seconds, 40kW/40kWh/1 hour and 30kW/2kWh/4 minutes, covering the second level, minute level, hour level of the full range of products, comprehensive technical indicators to reach the international leading level。The product energy storage time has jumped from the second level to the 15-minute level and the 2-hour level, leading the global flywheel technology revolution。

　 Huachi will integrate its own development into the national energy strategic needs, focus on the goal of carbon peak and carbon neutrality, actively serve the transformation and upgrading of the national energy industry, actively carry out new power system research with new energy as the main body, continue to promote energy storage technology innovation, and make greater contributions to the development of China's energy and power transformation。

　 Magnetic levitation energy storage flywheel has 10 million charge and discharge cycle life, zero attenuation, is not affected by the environment and temperature, green environmental protection and other characteristics，Applied to power curve optimization of various energy sources，Meet the high frequency, fast, repeated charge and discharge requirements of primary and secondary power frequency modulation，It provides the best solution for various application scenarios such as frequency modulation and peak regulation。

　 Application fields: joint frequency modulation of primary and secondary energy storage in thermal power plants, flexibility improvement of thermal power units, primary frequency modulation of new energy stations, independent energy storage frequency modulation power stations, deep peak modulation of thermal power plants, etc。
