  • Stability analysis of the Cable Core of a 10 kA HTS DC power Cable used in the electrolytic aluminum industry
    IEEE Transactions on Applied Superconductivity, 2015
    Co-Authors: Dong Zhang, Shaotao Dai, Fengyuan Zhang, Yuping Teng, Zhiqin Zhu, Xi Xu, Weiwei Zhou, Liangzhen Lin

    Abstract:

    © 2002-2011 IEEE. High temperature superconducting (HTS) dc power Cable shows a wide application prospect in the field of power transmission for its nearly lossless and rather high capacity. IEE has installed a 360-meter long high temperature superconducting (HTS) dc power Cable at the self-supply power plant of Zhongfu Industrial Company Ltd. in Gongyi, Henan and the system has operated for two years. The Cable connects a 19.5 MVA/1.5 kA silicon-controlled rectifier, which connects with a 110 kV/1 kV transformer, to the bus bar of an electrolytic aluminum cell. It is designed to carry 10-kA current and the voltage is 1300 V. The HTS dc power Cable Core consists of five conductor layers wound with the spliced Bi-2223 wires with the length of 40 km. The Cable Core has five layers and 23 HTS wires in each layer with the outer diameter of 45 mm. The HTS dc power Cable is fabricated with the spliced superconducting wires which will have effect on the overall superconductivity. Also, since dc output of the rectifier contains a proportion of the ac harmonic ripple, the large dc and small ac will generate the loss in the Cable Core. In the operation of the 10 kA HTS dc power Cable, anode effect will occur in electrolytic aluminum tank, which will lead to a large fault current in the Cable and even lead to the power off protection. In this paper, stability of the spliced Bi-2223 wire, stability of the Cable Core under the cold shrinkage force, loss under the large dc and small ac ripple are analyzed by the theoretical and experimental methods. The test results of ac ripple loss, anode effect, and stable operation are also presented.

    Abstract:

    IEE has installed a 360-m-long high-temperature superconducting (HTS) dc power Cable at the self-supply power plant of Zhongfu Industrial Co., Ltd. in Gongyi, Henan. The Cable connects a 19.5 MVA/1.5 kA silicon-controlled rectifier, which connects with a 110 kV/1 kV transformer, to the bus bar of an electrolytic aluminum cell. It is designed to carry 10 kA current and the voltage is 1300 V. The HTS dc power Cable Core consists of five conductor layers wound with the spliced Bi-2223 wires with the length of 40 km. The Cable Core has five layers and 23 HTS wires in each layer with the outer diameter of 45 mm. As the items in this project, testing of 4 to 5 m length prototype Cables, including a 5 m prototype Cable fabricated before the 360 m power Cable and a 4 m prototype Cable intercepted from the 360 m HTS power Cable, is conducted. These prototypes are used to assess the design program, fabrication process, and performance of the 360 m/10 kA HTS power Cable including steady state operation at the 10 kA design current and overcurrent fault capability. The critical current of the 5 and 4 m HTS power Cable reach 14.3 kA and 13.8 kA at 77 K, 1 μV/cm, respectively. In this paper, the design parameters and fabrication of the 360 m/10 kA HTS dc power Cable conducted by IEE are presented. The Cable system, installation process and the summary of the results from the testing of 4 and 5 m prototype Cables are described. In addition, details of the initial cool-down process and energizing are presented.
