      Aspects to take into account in the application of mechanical calculation to high temperature low sag conductors 

      Albizu Flórez, Igor; Mazón Sainz-Maza, Angel Javier; Valverde Santiago, Víctor; Buigues Beraza, Garikoitz (The Institution of Engineering and Technology, 2010-05)
      Reconductoring with high temperature low sag (HTLS) conductors is an alternative to the traditional uprating methods. The obtained rating increase depends on the mechanical and thermal behaviour of the conductor. In this ...

      Forecast Ratio and Security Analysis of Rating Forecasting Methods in an Overhead Line 

      Albizu Flórez, Igor; Fernández Herrero, Elvira; Mazón Sainz-Maza, Angel Javier; Alberdi, Rafael (The Institution of Engineering and Technology, 2017-01-26)
      The actual line rating in overhead lines varies with weather conditions. When a utility defines a rating value for the operation of the line, it takes into account both the security and the forecast ratio. The defined ...

      Influence of the conductor temperature error on the overhead line ampacity monitoring systems 

      Albizu Flórez, Igor; Fernández Herrero, Elvira; Mazón Sainz-Maza, Angel Javier; Bengoechea Aresti, Janire (The Institution of Engineering and Technology, 2011-04)
      Many real time overhead line ampacity monitoring systems are based on the calculation of the wind speed. The wind speed is obtained from the conductor temperature. The conductor temperature can be measured directly or it ...

      Simulación de sistemas Multi-Agente mediante un esquema Monte Carlo basado en ecuaciones diferenciales ordinarias 

      Zulueta Guerrero, Ekaitz; González González, Asier; López Guede, José Manuel; Calvo Gordillo, Isidro (Elsevier, 2011-07)
      [ES] En este trabajo se expone una metodología para modelar un sistema Multi-Agente (SMA), para que sea equivalente a un sistema de Ecuaciones Diferenciales Ordinarias (EDO), mediante un esquema basado en el método de Monte ...

      Sliding mode control law for a variable speedwind turbine 

      Barambones Caramazana, Oscar; González de Durana García, José María; Alkorta Egiguren, Patxi; Ramos Hernanz, José Antonio; De la Sen Parte, Manuel (WSEAS, 2011)
      Modern wind turbines are designed in order to work in variable speed operations. To perform this task, wind turbines are provided with adjustable speed generators, like the double feed induction generator. One of the main ...
