چکیده
The carbon neutrality goal of achieving net-zero by 2050 has sparked significant interest in offshore wind farms. With the farms installed > 100 km away from seashore, underground power transmission infrastructure is a necessity. Considering cable length and low net effective losses, high-voltage direct-current (HVDC) system chosen for this study. Also being lossless DC operation, HVDC cables are considered to be made out high-temperature superconductor (HTS) material. But, unlike copper/aluminium, HTS material sharp transient behaviour as function operating current, temperature field. Thus, under conditions, fault current ramps up, can lead an increase temperature, causing either degradation or permanent damage cable. In paper, model been developed MATLAB/Simscape coupling both electrical thermal models. For study, long coaxial kV/1 GW modelled lumped element distributed with elements compare evaluate parameters along length. include distribution, resistance, critical losses at different spots throughout To simulate condition, line-to-ground (LG) distribution between copper former tapes studied. Using model, maximum coolant superconducting state evaluated presented. comparison displayed values.

A High Temperature Experimental Characterization Procedure for Oxide-Based Thermoelectric Generator Modules under Transient Conditions
The purpose of this study is to analyze the steady-state and transient behavior of the electrical and thermal parameters of thermoelectric generators (TEGs). The focus is on the required wait-time between measurements in order to reduce measurement errors which may appear until the system reaches steady-state. By knowing this waiting time, the total characterization time can also be reduced. Th...
