摘要

本文重点介绍用于冷却 10-Mvar 级 HTS DSC 的远程低温氦循环系统。该低温系统为升级版,可提供约 200 W@20 K 的冷却功率。两个低温氦鼓风机用于克服压降。循环回路分为两个分支,每个分支中的三个冷却器并联安装,然后作为一个整体串联到一个氦鼓风机上。此外,还介绍了冷却系统的详细设计、结构参数和优化。在与 10-Mvar HTS DSC 转子部分耦合的实验测试中,首先用液氮将磁体预冷至约 110 K,然后通过循环氦气进一步冷却至约 34.5 K。不久的将来,10-Mvar 级 HTS DSC 将被安装、测试并并入电网,投入实际应用。

Remote cryogenic helium gas circulating cooling system for a 10-Mvar class HTS dynamic synchronous condenser

This paper focuses on the remote cryogenic helium circulating system for cooling the 10-Mvar class HTS DSC. The cryogenic system is an upgraded version to provide a cooling power about 200 W@20 K. Six cryogenic cryocoolers are employed as the cold source. Two cryogenic helium blowers are used to overcome the pressure drop. Circulating loop is divided into two branches, of each three coolers are installed in parallel and then as a whole connected to a helium blower in series. The detailed design, structure parameters, and optimization of the cooling system were described as well. In the experimental tests coupled with the rotor section of 10-Mvar HTS DSC, the magnet was firstly pre-cooled to about 110 K with liquid nitrogen, and then further cooled to around 34.5 K by the circulating helium gas. In the near future, the 10-Mvar class HTS DSC will be installed, tested and integrated into the power grid for practical application.
