高温超导（HTS）电缆系统有望成为改善电网的解决方案，美国正在进行三个实际电网示范项目。其中之一是纽约州奥尔巴尼的高温超导电缆项目，涉及安装和运行一个350米的高温超导电缆系统，容量为34.5千伏，800安培，安装在国家电网电力公用事业系统的两个变电站之间。一条320米长的电缆和一条30米长的电缆安装在地下管道中，并通过接头或拱顶中的接头连接在一起。在该项目的一期工程中，电缆采用DI-BSCCO线，采用3芯合一的低温恒温器结构。HTS电缆系统安装后，于2006年7月20日开始并网作业，并在无人值守的情况下成功运行至2007年5月1日。在第二阶段，30米的部分被2G （YBCO）电缆取代。2G电缆是用SuperPower公司的YBCO涂层导体在三芯一体低温恒温器中制造的。更换30米段后，重新组装接头和一个端接，并成功完成了初始冷却、临界电流测量和直流耐压试验等调试试验。调试测试后，HTS电缆系统与30米YBCO电缆和320米DI-BSCCO电缆于2008年1月8日重新通电，并开始在现场公用事业网络中运行。本文介绍了奥尔巴尼高温超导电缆工程的最新情况。
High-temperature superconducting (HTS) cable systems are expected to be a solution for improvement of the power grid and three demonstration projects in the real grid are underway in the United States. One of these is the Albany, NY HTS Cable Project, involving the installation and operation of a 350 meter HTS cable system with a capacity of 34.5 kV, 800 A, installed between two substations in National Grid's electric utility system. A 320 meter and a 30 meter cable are installed in an underground conduit and connected together by a joint, or splice in a vault. In Phase I of this project, the cables were fabricated with DI-BSCCO wire in a 3-core-in-one cryostat structure. After the installation of the HTS cable system, the in-grid operation began on July 20, 2006 and operated successfully in unattended condition through May 1, 2007. In Phase II, the 30 meter section was replaced by a 2G (YBCO) cable. The 2G cable was fabricated with SuperPower's YBCO coated conductors in a 3-core-in-one cryostat. After replacement of the 30 meter section, the joint and one termination were reassembled and the commissioning tests that included initial cooling, critical current measurement and DC withstand voltage test were completed successfully. After the commissioning tests, the HTS cable system with a 30 meter YBCO cable and a 320 meter DI-BSCCO cable was re-energized on January 8, 2008 and started again to operate in a live utility network. This paper describes the latest status of the Albany HTS cable project.
