Application Prospect of the Second High Temperature Superconductor Cable in Power Network

新能源变革背景下,超导输电技术将成为解决现有输电网络所面临挑战的主要方式之一。与传统电缆相比,超导电缆具有损耗低、容量大、重量轻、无火灾隐患和电磁污染等优点,为低损耗、大容量、高效率输电提供了有效途径。本文介绍了二代高温超导带材和电缆的基本结构及发展历程,结合目前的研究现状分析了二代高温超导电缆在输电系统中的应用前景。

As the age of new energy is coming, the superconducting technology is of great importance to solve the challenges the transmission network will face. Compared with the normal cable, the superconducting cable has advances of low losses, large capacity, light weight, small size, and no fire hidden trouble and electromagnetic pollution. It provides an effective way to transmit electricity with high efficiency, large capacity and low losses. In this paper, the history and structure of the second generation high temperature superconductor cables are introduced. Based on the researching progress in and outside China, the application prospect of the 2G HTS cables in the transmission network is analyzed.
