| Sumario: | The following paper will provide valuable information about the operations and maintenance costs and the different strategies to carry out the maintenance activities. First of all, a market study of the wind power installations in Europe is presented, in order to have an approach on which is the situation in the current market: wind power capacity installed, the most used wind turbine size and the investments done by each country. Secondly, a distribution and analysis of the basics costs of wind energy is carried out, with the main purpose of having an overview about all the costs of a wind farm. In third place, the operation and maintenance costs, the main topic of the thesis, are introduced and explained in a deeper way, giving different approaches to classify this costs. Then, a first approach to a strategy to reduce O&M costs is given: combining the maintenance activities with the harvest mussel. Consecutively, an analysis of the O&M costs is carried out taking into account different drive trains and types of generators, in order to see how the different generators affect to different wind farms located near and far from shore. Follow up, another study about the failure rate of each subassembly of the wind farm, the repair times and the unscheduled maintenance is analysed. With this information, the components who contribute the most to the O&M costs will be highlighted. After that, the report will move on to show which is the best strategy and the equipment that must be chosen for each wind farm with different characteristics in order to reduce the O&M costs. Therefore, for each strategy, the repair costs, the revenue losses and the total O&M costs will be given. Finally, the report will give an approach to find out a feasible maintenance solution for the blade wind turbine by determining an inspection interval and a repair limit. |
