Motivation
The increasing size of wind turbines is leading to problems with vibrations and deformations during operation. This creates a need for comprehensive monitoring of the turbines so that vibrations and deformations – particularly of the blades and towers – can be taken into account in control systems and maintenance. Monitoring systems currently available on the market use high-cost sensors, which make comprehensive measurement of vibrations and deformations across the entire wind turbine uneconomical. Furthermore, there is a lack of intelligent analysis of the recorded data to meet the wind energy sector’s growing need for condition monitoring.
Approach
The approach initially involves analysing the requirements for the ‘wind turbine’ system from various perspectives, with particular emphasis on cost-efficiency, scalability, sustainability and yield enhancement. Demonstrators for the measurement technology are developed in accordance with the requirements using systematic product development methods and are iteratively improved through laboratory tests. The data transmission, storage and evaluation platform are also implemented as a demonstrator. The measurement technology is then installed on various wind turbines to be validated in field tests. Based on the results, the demonstrators are further optimised for use under real-world conditions on a wind turbine.
Objective
The aim of the project is to develop an intelligent sensor system with an integrated evaluation algorithm based on low-cost sensors. The sensor system is intended to combine three individual measurement systems for both vibration and deformation measurement. An evaluation platform is to enable the joint processing of sensor data and the flexible integration of various analysis modules. This will enable the operation and maintenance of wind turbines to be adapted to their vibration and deformation behaviour, thereby increasing efficiency and service life. The University of Bremen is contributing in particular to the further development of a low-cost solution for measuring accelerations in industrial environments, in order to enable scalable vibration and deformation monitoring.
