Assessment of conductor thermal models for grid studies
(The Institution of Engineering & Technology, 2007)
: Existing EMS applications resort to static network models built upon constant resistances whose values are specified beforehand. However, the steady-state thermal balance of overhead conductors requires that ohmic ...

Towards a New Model of Evaluation of Transformation Losses in Solar Orchards
(European Association for the Development of Renewable Energies, Environment and Power Quality, 2007)
In this article is analyzed the economic yield that would turn out from replacing the conventional transformers currently used on solar orchards by others of higher performance. In this way, the losses would be ...

Wavelet-Fourier analysis of electric signal disturbances
(ICREPQ, 2007)
The Fourier transform usually has been used in the past for analysis of stationary and periodic signals. Its interest is the knowledge of spectral components existing in a waveform; it doesn't matter the moment where they ...
