This paper presents the skin effect impact on active power losses in sheathless single-core cables/wires supplying nonlinear loads. There are significant conductor when current has a distorted waveform (e.g., diode rectifiers). The authors present new method for loss calculation. obtained results have been compared to IEC-60287-1-1:2006 + A1:2014 standard and based Bessel function. For all meth...

Historical meteorological data indicates, that our weather is becoming more and extreme. For the electrical utility operators (Distribution System Operators - DSOs Transmission TSOs), these changes arise in new operation challenges need to be addressed. example, frequent icing phenomenon affects all components of power line by a significant mechanical overload: it endangers conductors, insulato...

fuel cells belong to an avant-garde technology family for a wide variety of applications including micro-power, transportation power, stationary power for buildings and other distributed generation applications. the first objective of this contribution is to find a suitable reduced model of a solid oxide fuel cell (sofc). the derived reduced model is then used to design a state estimator. in th...
