Patent number: 9762051Abstract: A current-limiting and power-flow control device according to the present invention includes a superconducting current-limiting element including a superconductor, a series capacitor, and a parallel circuit. The series capacitor is connected in series with the superconducting current-limiting element. The parallel circuit includes a reactor connected in parallel with a series circuit including the superconducting current-limiting element and the series capacitor. Accordingly, overcurrent at the time of occurrence of a fault causes transition of the superconductor of the superconducting current-limiting element to the normal conducting state, and thus causes autonomous current-limiting operation of the superconducting current-limiting element. Thus, application of an excessive load across the terminals of the series capacitor due to the aforementioned fault can surely be prevented.Type: GrantFiled: March 26, 2014Date of Patent: September 12, 2017Assignee: Sumitomo Electric Industries, Ltd.Inventors: Shigeki Isojima, Shuichi Nogawa, Kouji Noguchi, Kazuhiro Kuroda
