高压直流输电网具有广阔的发展潜力，特别是考虑到海上风电场的发展。在本文中，我们考虑网状HVDC电网。网状网络增加了故障电流。这些非常高的电流是系统的缺点，并且故障清除过程需要新技术来断开巨大的直流电。因此，高速保护和开放系统目前在几个机构中进行研究。考虑到差动保护系统，可以使用各种开放系统。但是，在这项研究中，超导故障限流器，使用高温超导磁带是用来减少显着巨大的电流被打破的直流断路器。非常精确的模型的模拟被用来证明的结论。
High Voltage Direct Current (HVDC) grids have a wide potential of development, especially considering the development of offshore wind power plants. In this paper, we consider meshed HVDC grids. Meshing networks increases the fault current. These very high currents are a drawback for the system, and the fault clearing process requires new technologies to break huge direct current. Therefore, high speed protection and opening systems are currently investigated in several institutions. Considering a differential protection system, various opening systems can be used. But, in this study, superconducting fault current limiters, using high temperature superconducting tapes are used to reduce the dramatically huge current to be broken by the DC breakers. Simulations with very accurate models are used to justify the conclusions.
