1. 21. Life-Cycle Cost Analysis for Offshore Wind Farms:Reliability and Maintenance.O&M Cost Drivers Analysis

   University essay from Institutionen för kultur, energi och miljö

   Author : Hector Trevino Cantu; [2011]
   Keywords : Offshore; wind farm; operations; maintenance; O M; life-cycle cost; reliability.;

   Abstract : Operations and maintenance (O&M) activities represent a significant share of the expenses during the lifetime of offshore wind farms. When compared to onshore wind farms, O&M costs are increased for the offshore case, as specialized vessels, weather windows and rough conditions mean more failures, downtime (decreasing availability), spare parts, and man-hours.

3. 22. Comparative LCA model on renewable power solutions for off-grid radio base stations

   University essay from KTH/Industriell ekologi

   Author : Anna Bondesson; [2010]
   Keywords : renewable energy; radio base station; life cycle assessment; LCA; hybrid power system; wind power; solar power; förnyelsebar energy; radiobasstation; livscykelanalys; LCA; hybridsystem för elgenerering; vindkraft; solenergi;

   Abstract : Globally, there are approximately 900 000 telecommunication radio base station sites (RBS-sites)located in areas without access to the electrical grid. Traditionally, these sites are powered by dieselgenerators, consuming large amounts of fossil diesel fuel. READ MORE

4. 23. Modelling of icing for wind farms in cold climate : A comparison between measured and modelled data for reproducing and predicting ice accretion

   University essay from Uppsala universitet/Luft-, vatten- och landskapslära

   Author : Erik Rindeskär; [2010]
   Keywords : ice accretion; icing of wind turbines; modelling of icing;

   Abstract : Wind farms are nowadays more often constructed in alpine terrain than earlier due to theprofitable wind resource as well as, often, less conflicting interests than in more denselypopulated areas. The cold climate poses a relatively new challenge to the wind power industrysince icing of the wind turbine blades and sensors may induce losses in production, increasethe wear and tear of the components, leading to a shortening of structural life time as well as itdecreases the availability and hence reducing the economical profitability for the owner.

5. 24. Maintenance management of wind power systems : Cost effect analysis of condition monitoring systems

   University essay from KTH/Elektroteknisk teori och konstruktion

   Author : Julia Nilsson; [2006]
   Keywords : ;

   Abstract : The wind power industry has experienced a large growth the past years. The growth mainly focus on a growing market, better economical conditions for wind power because of political decisions and the development of large wind turbines and offshore farms. A goal is to increase reliability for turbines. READ MORE

6. 25. Lifetime Monitoring of Wind Turbines

   University essay from Lunds universitet/Institutionen för reglerteknik

   Author : Lars Nilsson; [2005]
   Keywords : Technology and Engineering;

   Abstract : The aim of this thesis was to design and implement a lifetime monitoring system for a GE Energy wind turbine. Monitoring the loads on the main components of a wind turbine makes it possible to keep the lifetime of the components monitored. This information can be used to enable more flexible planning of a wind turbine's maintenance. READ MORE
