Optimal Dynamic Analysis of Electrical/Electronic Components in Wind Turbines

Abstract

Electrical and electronic components are very important subcomponents in modern industrial wind turbines. Complex multimegawatt wind turbines are continuously being installed both onshore and offshore, continuously increasing the demand for sophisticated electronic and electrical components. In this work, most critical electrical and electronic components in industrial wind turbines have been identified and the applicability of appropriate condition monitoring processes simulated. A fault tree dynamic analysis has been carried out by binary decision diagrams to obtain the system failure probability over time and using different time increments to evaluate the system. This analysis allows critical electrical and electronic components of the converters to be identified in different conditions. The results can be used to develop a scheduled maintenance that improves the decision making and reduces the maintenance costs.

Acoustic Maintenance Management Employing Unmanned Aerial Vehicles in Renewable Energies

“…This is the dominant noise of the WTs. Nowadays, the blades are becoming increasingly large due to the size of blades is directly related to the productivity [13]. The larger blades are usually louder than the small ones.…”

“…The operators take decisions according to analytics methods [6][7][8], where in fault detection and diagnosis have been studying novel techniques in the last few years [9][10][11]. In order to improve the O&M process, condition-based maintenance systems are widely employed for the wind energy systems [12][13][14]. These systems allow useful information about the condition of the WTs to be extracted.…”

Optimal Productivity in Solar Power Plants Based on Machine Learning and Engineering Management

“…It is necessary to find efficient methodologies and tools to reduce the O&M costs and ensure the availability of the solar panels. These new tools should be applicable to preventive and predictive maintenance [10][11][12][13].…”

“…The operators take decisions according to analytics methods [10,16,17], where in fault detection and diagnosis have been studying novel techniques in the last few years [18][19][20]. Condition-based maintenance systems are widely employed for the wind energy systems to improve the O&M process [13,21,22]. These systems allow useful information about the condition of the panels.…”

Maintenance Management in Wind Turbines by Monitoring the Bearing Temperature

“…dition, WTs are made up of various complex systems that give rise to a whole, therefore, the failures or damages can occur in various parts of the system [1,5,6].…”
