HTS Cable Optimized Design And Application Development

With the rapid economic development and social living standards continue to improve, the demand for energy is growing, the quality of power requirements have become more stringent, nearly lossless power transmission, power quality assurance is a hot issue.Third International Conference on Washington Refrigeration Onnes first formally proposed the "superconducting state" in September1913. HTS (High Temperature Super-con conducting) has been found since1986in energy, electricity, health care, defense, information, and many other important applications demonstrated value. Due to high temperature superconducting cable has nearly lossless transmission and efficient transmission efficiency, high-temperature superconducting cable at high current, long-distance power transmission, etc. play an important role. Among them, the high-temperature superconducting AC power loss during transmission is an important research topic.At first, this paper introduces the basic situation of high-temperature superconductivity and application background, high-temperature superconducting cable in the field of power electronics application presentation. Analysis of the high-temperature superconducting cable of the general structure and characteristics Theoretical derivation properties of superconducting cable carrier, focusing on analysis of the superconducting cable AC characteristics and lossSecondly, we derive the equivalent electromagnetic effects HTS cable through the literature review, research, a large number of scholars through theoretical analysis and experimental results show that, to the conductor layer around the angle (3, and the winding direction of a conductor layer to optimize the radius r object, using intelligent optimization algorithm can reduce the population exchange losses.Again, for each of the conductive layer HTS cable will result in uneven distribution of current exchange loss increases questions to each of the conductive layers around the corner, the radius of the winding direction and layers to optimize object to the current equilibrium distribution layers establish objective optimization function, a superconducting cable of the mechanical properties and the critical current as constraints flies through improved optimization method, the cable conductive layer parameter optimization, the experiment proved feasible.Finally, on the application of superconducting cables in real applications and development trends, a brief analysis of the development prospects of superconducting cables forecast.It also noted that the lack of high-temperature superconducting cables.
