  1. 6. Emergency Power for Wind Turbine Yaw System - Project initialization tool

    University essay from Lunds universitet/Industriell elektroteknik och automation

    Author : Vigan Spahiu; [2020]
    Keywords : Technology and Engineering;

    Abstract : The Yaw Power Backup System (YPBS) is a safety system that needs to be incorporated in the Wind Power Plant (WPP) in order to provide emergency power during a power outage. The YPBS enables the Wind Turbine Generator (WTG) to perform a yawing operation in extreme weather conditions. READ MORE

  3. 7. Dynamic transformers rating for expansion of expansion of existing wind farms

    University essay from KTH/Elektroteknisk teori och konstruktion

    Author : Oscar David Ariza Rocha; [2019]
    Keywords : Dynamic transformer rating; wind energy; loss of life; wind farm expansion;

    Abstract : Distribution system operators face the challenge to connect users rapidly to the grid and the opportunity to reduce costs for new connections. A method to enhance network operation and planning is dynamic transformer rating (DTR), which considers load and temperature variations to increase the rating of the transformer while maintaining in safe operation.

  5. 9. Coupled Dynamic 3D Simulation of Short Circuit Forces

    University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Author : PRITESH DULABHAI HADIYA; [2013]
    Keywords : Two dimensional axisymmetric; Three dimensional model; Comsol Multiphysics; Transformer short circuit.;

    Abstract : The purpose of this work is to find the effect of short circuit current on displacement inside the transformer’s winding. In this work two different winding has been investigated by creating 2D and 3D simulation models of them. In order to solve the problem various assumptions/simplification has been taken and verified.
