SBIR Phase II: Reliable, Low Cost Support System for Flywheel Energy Storage

该小型企业创新研究第二阶段项目将开发一个飞轮储能系统（FESS）原型，该系统将利用第一阶段项目中开发的创新被动非接触式轴承。 这种新型的被动磁支撑和阻尼（PMSD）系统由集成的刚度和阻尼元件的配置，克服了以前的系统的最重要的问题。 新的轴承技术将导致一个更有效，更可靠，更便宜的FESS比目前可用。 由此产生的FESS将促进在偏远和/或恶劣环境中使用替代能源系统。 第二阶段的工作将集中在两个目标：（1）的改进和实验验证的设计方程预测的PMSD性能;（2）的开发，安装和测试的PMSD系统的原型FESS。 原型的FESS系统将是由商业化合作伙伴提供的商业单元，并进行修改以适应新技术。 该合作伙伴目前生产用于商业电能质量和不间断电源应用的FESS。 阿拉斯加科学和技术基金会和商业化合作伙伴已作出后续供资承诺和其他协议，以开展更多的技术工作和第三阶段商业化。 除了为替代能源系统提供存储之外，结合PMSD技术的FESS还有许多商业应用，包括公用事业负载均衡和不间断电源（UPS）。 商业化合作伙伴预计，第一阶段所展示的技术和成本优势的结合将使市场迅速接受，并鼓励FESS在新市场中的应用。 PMSD技术也适用于涡轮分子泵（TMP）。 它们用于制造硅芯片和需要高真空的科学仪器。 预计到2005年，这些领域的市场渗透率将超过每年18，000台，到2009年将超过每年30，000台。

This Small Business Innovation Research Phase II project will result in the development of a prototype flywheel energy storage system (FESS) utilizing the innovative passive, non-contacting bearing developed in the Phase I project. This new type of passive magnetic support and damping (PMSD) system consists of integrated stiffness and damping elements in a configuration that overcomes the most significant problems of previous systems. The new bearing technology will result in a more efficient, more reliable, and less expensive FESS than is currently available. The resulting FESS will facilitate the use of alternative energy systems in remote and/or hostile environments. Phase II efforts will focus on 2 objectives: (1) The refinement and experimental validation of design equations predictive of PMSD performance; and (2) The development, installation, and testing of PMSD systems in a prototype FESS. The FESS system for the prototype will be a commercial unit provided by the commercialization partner, and modified to accommodate the new technology. The partner currently manufactures FESS for commercial power quality and uninterruptible power supplies applications. Follow-on funding commitments and other agreements have been secured from the Alaska Science and Technology Foundation and from the commercialization partner to pursue additional technical work and for Phase III commercialization. In addition to providing storage for alternative energy systems, there are numerous commercial applications for FESS incorporating the PMSD technology including utility load leveling and uninterruptible power supplies (UPS). The commercialization partner expects that the combination of technical and cost advantages demonstrated in Phase I would enable rapid market acceptance and encourage application of FESS in new markets. The PMSD technology is also applicable to turbo-molecular pumps (TMPs). These are used in the manufacture of silicon chips and in scientific instrumentation requiring high vacuums. Predicted market penetration into these areas is in excess of 18,000 units per year by 2005 and in excess of 30,000 units per year by 2009.
