Electricity generation from renewable energy sources can be constrained by the static thermal rating of existing overhead lines. A potential solution is dynamic line rating based on the line’s temperature. The conductor temperature can be calculated from the line’s resistance, if measured accurately and in real-time. In this paper three suggested methods for impedance determination from synchro...
1800A/3.3kV IGBT module with the highest current rating was developed. Advanced Trench HiGT structure was used to achieve low loss characteristics. Module electrical and thermal characteristic were optimized in order to reduce thermal resistance and parasitic inductance. The current ratings of new IGBT module can be increased by 20% from the conventional product type.
thermal barrier coatings (tbcs) are used to provide thermal insulation to the hot section components of gas turbines in order to enhance the operating temperature and turbine efficiency. hot corrosion and thermal shocks are the main destructive factors in tbcs which comes as a result of oxygen and molten salt diffusion into the coating. in this thesis atmospheric plasma spraying was used to dep...
In this paper the Quasi-Static poro-thermoelasticity model of a hollow and solid sphere under radial symmetric loading condition (r, t) is considered. A full analytical method is used and an exact unique solution of the Quasi-Static equations is presented. The thermal, mechanical and pressure boundary conditions, the body force, the heat source and the injected volume rate per unit volume of a ...
