other industries, is transferred to wind power systems. The focus lies on theutilization of CMS used to continuously monitor the condition of the wind turbineequipment. CMS data is analyzed in order to detect incipient failure and developmethods for optimal condition-based maintenance in a systematic way.This research project aims to continue on previous research performed at KTHand within the research group of reliability–centred asset management (RCAM)under the direction of Lina Bertling. Within the RCAM group research has beenperformed within the topics of applied reliability theory for electric power systemand equipment from 1997 including three PhD theses: Bertling 2002, Lindquist2005, Hilber 2005, and several tech lic theses and master theses. The aim of thisproject is to continue the research track into the field of wind power applications,also involving an ongoing PhD student project within Vindforsk II by FrancoisBesnard and Lina Bertling. During the autumn a new post-doc project isformulated for Dr. Katharina Fischer to join the group.Power Cluster – Work package 2 – Business/Grid study of the off-shore windfarms in the North SeaParticipant: Tuan LeSponsors: EU - INTERREG IV B North Sea Region ProgramWhen large-scale renewable energy resources are integrated to the power grid ofthe countries in the North-Sea region, the existing power systems could easilyexperience overloading and power/voltage fluctuation problems, since they havenot been designed to take up as much energy from the remote ends of the grids,(i.e. offshore.) In addition, the fluctuating nature of renewable energy, for examplewind energy, could worsen the situation. The grids at these points are often lowvoltage and relatively weak. They are not ready to take on large-scale renewablepower injection. This project focuses on development of a proposal for the offshorewind power grid and evaluates its effects on the existing on-shore grid in theNorth Sea region. The project also focuses on evaluation of the surplus benefitswhen the North Sea Wind Power Grid is connected to the countries around theNorth Sea, in terms of new opportunities for more energy trading between thecountries and other market related issues.PhD student projectsAnalysis of Wind Park High-Frequency Electrical OscillationsParticipants: Tarik Abdulahovic, Torbjörn Thiringer, Ola Carlson,Sponsor: VindforskThis project investigates the generation, presence and propagation of highfrequencydisturbances in a sea-based wind park consisting of modern convertercontrolledwind turbines.28 |
