Advances in superconductor technology make the prospect of economical operation of high temperature superconducting (HTS) power cables a practical concept for grid applications in urban centers. With more advanced cable designs being developed and commercialized, their geometrical features and dynamic behavior are becoming increasingly complicated to be modeled. This brings new challenges as the complex structure of HTS power cables significantly increases the computation power needed to perform simulations. In this paper we develop a two-dimensional open source simulation code based on the finite difference method which is solved by means of the alternating direction implicit routine. The algorithm has been written in MatLab programming language. The method improves computational performance and simulation time. In addition, this enables the creation of open-source simulation codes. A three-phase concentric HTS cable design has been chosen for the development of the code, nevertheless the model can be employed for any cable design. The results indicate an efficient, stable and powerful simulation code. During the development no numerical instabilities have been found. Besides that, the model is able to deliver quantities that are experimentally difficult to access. Simulation files are available for the scientific community on the HTS Modeling Workgroup webpage. 1 1 Simulation files can be downloaded.here.

This article uses a distributed optical fiber temperature measurement system (DTS, Distributed Temperature Sensing) to fix the temperature measurement optical fiber on the surface of the power cable, collect the real-time operating temperature of the power cable, conduct the ampacity test, and analyze the cable laying method and depth, soil temperature, Soil thermal resistance coefficient, cable spacing and irradiation strength and other test conditions, the impact on the current carrying capacity of power cables. According to the real-time monitoring temperature of the cable, the alarm can be made when the cable temperature is too high or the temperature rise speed is too fast. And on the basis of determining the working temperature and load operating conditions of the cable conductor core, dynamically calculate the current carrying capacity of the cable, which is conducive to improving the performance of the power cable and increasing the load capacity of the power cable.

The paper discusses important issues such as high-performance materials, electrical tree aging, space charge, insulation structure and technology, and cable operation detection in cable research and development. It is believed that DC cables will be used in power transmission for a long time in the future. It will receive more and more attention, but it is also facing the problems of insulation reliability and the development of new materials due to space charge and nonlinear temperature characteristics. The paper analyses the main reasons for the failure of power cables in the smart grid, and proposes several advanced power cable fault diagnosis technologies, and studies their principles and applications in order to improve the efficiency of fault diagnosis of the smart grid and protect the power grid. Operational reliability.
