SBIR Phase I: Third Generations Flywheels for Electricity Storage

这个小型企业创新研究第一阶段项目将设计和测试磁悬浮储能飞轮的电动机/发电机子系统，可扩展到每单位兆瓦时，有可能大大减少美国因电力波动和停电而造成的经济损失。根据电力研究所的数据，这些损失超过1000亿美元/年。该公司的研究目标是开发低成本的第三代飞轮-“动力环”-在紧凑的尺寸中具有巨大的功率和容量。多兆瓦时的机组似乎是可行的。第一阶段项目的预期结果是设计一个高功率密度的电动机/发电机，将其集成到功率环设计中，对其对环稳定性的影响进行动态分析，并设计一个小规模的电动机/发电机。反对新的输电线路和发电厂，环境限制和过高的成本减缓了系统的改进。储能飞轮可以提供一种清洁、经济的替代方案，如果它们的功率和容量比目前的几百千瓦和几千瓦时的限制高得多，就可以大幅减少经济损失。但是高容量的第一代（钢）飞轮太大而不具有成本效益，并且第二代（复合材料）飞轮不能按比例放大。

This Small Business Innovation Research Phase I project will design and test the motor/generator subsystem for a magnetically levitated electricity storage flywheel, scalable to megawatt-hours per unit, with the potential to greatly reduce US economic losses due to electric power fluctuations and blackouts. According to the Electric Power Research Institute, these losses exceed $100 billion/year. The company's research objective is to develop low cost third generation flywheels - "Power Rings" - with enormous power and capacity in a compact size. Multi-megawatt-hour units appear feasible. Anticipated results of this Phase I project are the design of a high power density motor/generator integrated into the Power Ring design, a dynamic analysis of its effects on ring stability, and a working small-scale version of the motor/generator.Opposition to new transmission lines and power plants, environmental restrictions, and exorbitant costs have slowed system improvements. Electricity storage flywheels could provide a clean, economical alternative and slash economic losses if they had much higher power and capacity than the present limit of a few hundred kW and a few kWh. But high capacity first generation (steel) flywheels are too massive to be cost effective and second generation (composite) flywheels cannot be scaled up.
