Problems solved by technology

[0003] At present, there are few conductor designs for superconducting DC cables, and there is no unified design criterion. Most superconducting DC cable conductor designs are still based on the guiding principle of superconducting AC cable conductor design - by allowing the current to be evenly distributed in each layers of superconducting tape to minimize AC losses

Abstract

The invention provides a simulation analysis method for current density distribution of a high-temperature superconducting direct-current system considering the overall utilization rate of a superconducting tape. Firstly, a three-dimensional model is established for a high-temperature superconducting direct-current cable conductor, current distribution on the superconducting conductor is obtainedby solving the three-dimensional model, the overall utilization rate of strips is improved by optimizing the screw pitch of the superconducting strips, current distribution on each superconducting strip is uniform, and the use amount of the strips is small.

Description

technical field [0001] The invention belongs to the field of superconducting cable design, in particular to a simulation analysis method for the current density distribution of a high-temperature superconducting conductor considering the utilization rate of superconducting strips. Background technique [0002] High-temperature superconducting cables can realize large-capacity current transmission with low transmission loss, and are an excellent way to realize energy transmission in a limited space. Since the superconducting DC cable has zero resistance, it can truly exert the performance of the superconducting cable. The use of superconducting cables alone requires corresponding cooling equipment, which increases the complexity of the power transmission system. The superconducting energy pipeline can transmit electric energy and liquefied natural gas at the same time, providing a relatively suitable low temperature environment for the operation of high-temperature supercond...
