自焦耳热损失出现以来，大规模电力网络发展的方向与增加电压值的历史非常相吻合。但是，高温超导（HTS）技术改变了该历史的方向。此外，HTS技术将由于其极高的电流密度而没有焦耳热损失，因此将迅速加速这种变化的速度。由于这些原因，已经讨论了许多不同类型的HTS电力传输应用，并开发了选定的项目。几十年来，HTS AC和DC电力传输应用的技术已经开发并接近工业化所需的水平。此外，其中一些应用程序已经安装，通电并在实际电力网络中运行。在本文中，我们报告了AC和DC功率传输的HTS应用中的当前状态和进度。特别是，本文着重于各种HTS电源应用中超导电缆的应用领域。在韩国，韩国电力公司NAJU旨在引入更多的新技术以开发韩国电力网络，并且认为HTS是下一代电力网的开发的关键因素，这将是它将将其发电的关键因素在本文中详细讨论。
The direction of the development of large-scale electric power networks has very much coincided with the history of increasing voltage values ever since the advent of Joule heat loss. However, a high-temperature superconducting (HTS) technology has changed the direction of that history. Furthermore, the HTS technology will rapidly accelerate the speed of such change due to its extremely high current density with no Joule heat loss. For these reasons, many different types of HTS electric power transmission applications have been being discussed, and selected items have been developed. Within a few decades, the technology of HTS ac and dc power transmission applications had already been developed and close to the required level for industrialization. Moreover, some of these applications have been installed, energized, and are operating within real power networks. In this paper, we report on the current status and progress in HTS applications of ac and dc power transmission. In particular, this paper focuses on the application field of superconducting cable among various HTS power applications. In South Korea, the Korea Electric Power Corporation, Naju, aims to introduce more new technologies in order to develop the Korean power network, and it believes that an HTS is a key factor in the development of the next generation of power grid, which will be discussed in detail in this paper.
