* 摘要 小行星9660113 这个小型企业创新研究第一阶段项目将开发一个电力电子接口模块，将能源连接到并联连接到公用事业系统的逆变器系统。具体来说，本设计工作将集中在这样一个接口模块连接超导储能（微型SMES）系统的逆变器系统。为了提高微型超导磁储能系统的输出功率，需要更高的磁电流。设计目标包括评估不同的拓扑结构和确定最佳解决方案。最终的额定功率将在5至10兆瓦的范围内。 微型SMES系统在国内和全球最大的增长领域之一是电能质量市场。电能质量问题可以在一系列客户位置或电力公用事业系统上得到解决。具有新型接口模块的微型SMES系统为这些问题提供了独特的解决方案，因为：1）能够连接到各种逆变器; 2）并联设备增加了额定功率; 3）这种更高的额定功率与并联逆变器相结合，允许在公用事业配电系统电压水平上开发应用。***

*** ABSTRACT 9660113 Kostecki This Small Business Innovation Research Phase I project will develop a power electronic interface module to connect an energy source to an inverter system connected in parallel to the utility system. Specifically, this design effort will focus on such an interface module for connecting a superconducting energy storage (Micro-SMES) system to an inverter system. Higher magnet currents are needed to increase the power output level of Micro-SMES systems. Design objectives include the evaluation of different topologies and determination of the optimal solution. The ultimate power rating will be up in the 5 to 10 MW range. One of the largest growing national and global areas for Micro-SMES systems is the power quality market. Power quality problems can be addressed in a range of customer locations or on the electric utility system. A Micro-SMES system with a new interface module offers a unique solution to these problems because of: 1) the ability to connect to a variety of inverters; 2) paralleling devices increases the power rating; and 3) this higher power rating combined with the parallel-connected inverters permits the development of applications at the utility distribution system voltage level. ***
