Wind turbines maintenance

Einally, there are a few analytical models in the literature that deal with wind turbines. Byon et al. (2010) consider use a Markov Decision Process (MDP) to determine the optimal maintenance strategy under stochastic weather conditions. To our knowledge, this is the first mathematical model for wind turbine maintenance however, it is in a land-based context. Haddand et al. (2010) use a MDP based on real options for the availability maximization of an offshore wind farm. This model takes a condition-based maintenance approach to identify the optimal combination of turbines to be maintained in the wind farm. Besnard et al (2011) formulate a stochastic model for opportunistic maintenance planning of offshore wind farms. They use stochastic optimization to optimize the planning of service maintenance activities to take advantage of low wind periods in order to reduce production loss while the turbines are offline. Besnard et al. (2013) also...

There are no electrolyzers developed specifically for operation with wind turbines. However, the rapid response of electrochemical systems to power variations makes them suitable "loads" for wind turbines. Industrial electrolyzers are designed for continuous operation, mainly because their elevated investment cost requires high-capacity factors for reasonable payback times, but they are subject to a considerable number of current interruptions through their lifetime due to occasional power interruptions, accidental trips of safety systems, and planned stops for maintenance. Current interruptions are more frequent in specialty applications, where electrolyzers supply hydrogen "on demand." Therefore, the discontinuous use of the equipment is not new, and most commercial electrolyzers may be used in intermittent operation although a significant performance decrease is expected with time. In fact, it is not power variation, but current interruptions that may cause severe corrosion problems to the electrodes, if the latter are not protected by the application of a polarization current when idle. 

Wind Power Plant A group of wind turbines interconnected to a common utility system through a system of transformers, distribution lines and (usually) one substation. Operation, control and maintenance functions are often centralized through a network of computerized monitoring systems, supplemented by visual inspection. This is a term commonly used in the United States. In Europe, it is called a generating station. 

Access is much more of a challenge than for wind turbines, and therefore the turbines are built with a modular design allowing critical components to be lifted out of the water for maintenance or repair. The plant generates 700,000 kWh of power per year, which is enough electricity for 35 homes. (Website www.e-tidevannsenergi.com).

Abstract This chapter will discuss advances in the properties, production and manufacturing techniques of the advanced synthetic fibre/polymer composite materials that are utilised in the manufacture of machines that produce sustainable energy. Furthermore, it will suggest methods for the repair, maintenance and recycling of advanced polymer composite wind turbine blades. 

For the repair of wind turbine blades, Gurit has developed the prepreg SPRINT , SparPreg , which requires no de-bulking. They have also developed the RENUVO blade-repair system for the repair and maintenance of wind turbine blades. SparPreg material is said to provide the following benefits in spar manufacture ...
