High voltage direct current (HVDC) transmission technology has begun to play a great role in power transmission industry over the last decade. However, short-circuit fault seriously threatens the safety of an HVDC network. In order to reduce the fault current level of an HVDC network, utilizing a superconducting fault current limiter (SFCL) was proposed by researchers and engineers worldwide. Recently, Guangdong Grid Company of China Southern Power Grid, Co. has led a project to develop a 160 kV/1 kA resistive type DC SFCL. As a middle-step objective, a 160 kV/1 kA laboratory prototype has been developed. Due to a facility with an adequate capacity for testing such DC equipment is practically inaccessible, the current limiting performance of the prototype cannot be tested with a straightforward current limiting experiment. In practice, effectual alternative methods have to be adopted. Since the AC half-wave impact method requires less equipment and cost than the DC impact method, we took on an AC half wave impact current method to evaluate the current limiting function of the prototype alternatively. In this paper, we report the procedures and results of these tests.

在过去的十年中，高压直流（HVDC）传输技术已开始在电力传输行业中发挥重要作用。但是，短路故障严重威胁了HVDC网络的安全。为了降低HVDC网络的故障电流水平，全球研究人员和工程师提出了利用超导故障电流限制器（SFCL）的建议。最近，南方电网公司广东电网公司领导了一个开发160 kV / 1 kA电阻型直流SFCL的项目。作为中间步骤的目标，已开发出160 kV / 1 kA的实验室原型。由于实际上没有足够的设备来测试此类直流设备，因此无法通过简单的限流实验来测试原型的限流性能。在实践中，必须采用有效的替代方法。由于交流半波冲击法比直流冲击法需要更少的设备和成本，因此我们采用交流半波冲击电流法来评估原型的限流功能。在本文中，我们报告了这些测试的过程和结果。
