Initial Condition Monitoring Experience on a Wind Turbine

  title={Initial Condition Monitoring Experience on a Wind Turbine},
  author={Eric Bechhoefer and Bruno Boucher},
The initial installation of a condition monitoring system (CMS) on a utility scale wind turbine produced a number of unexpected results. The CMS was installed on the TechnoCentre éolien Repower MM92. The installation allowed testing of a MEMS (microelecctromechanical system) based sensor technology and allowed and in-depth analysis of vibration data and revolutions per minute (RPM) data. A large 3/revolution effect, due to tower shadow and wind shear, required the development of an enhanced…

Performance and condition monitoring of tidal stream turbines

Research within the Cardiff Marine Energy Research Group (CMERG) has considered the integrated mathematical modelling of Tidal Stream Turbines (TST). The modelling studies are briefly reviewed.

Choosing the Best Vibration Sensor for Wind Turbine Condition Monitoring

Conservative estimates suggest that there are at least one-quarter of a million wind turbines currently installed worldwide. In the next four years, the global wind turbine market is expected to add

An Approach to Supporting Maintenance of Offshore Wind Turbine Blades

Offshore wind turbine blades suffer from various faults such as blade angle asymmetry, icing, and bends. Replacement of rotor blades normally involves heavy transportation (e.g., vessel and crane),

Proactive maintenance of offshore wind turbine blades using knowledge-based force analysis

The approach solves the semantic ambiguity of offshore wind information and provides the possibility to monitor the performance of wind turbine blades in real-time, leading to advanced alarms when needed, and can be adapted and applied for other wind turbine components.

Feasibility of Low-cost Vibration Monitoring for Ground Vehicles

This paper reports empirical investigation for the feasibility of MEMS accelerometers for PHM application in monitoring of ground vehicles on the use case of diesel engine monitoring. The failure

Seismic response of a full-scale wind turbine tower using experimental and numerical modal analysis

Wind turbine technology has developed tremendously over the past years. In Egypt, the Zafarana wind farm is currently generating at a capacity of 517 MW, making it one of the largest onshore wind

Wind Turbine Monitoring and Fault Diagnosis by Can Protocol

The system with ARM and CAN protocol is declared to avoid the problems which occur in the wind turbine and reduce the possibility of fault occurrence and increase the monitoring of wind turbine.

Signal processing techniques to improve an Acoustic Emissions sensor

This paper hypothesizes that the AE signature is the result of some forcing function (e.g. periodic motion in the case of rotating machinery) and by using analog signal processing to demodulating theAE signature, one can reconstruct the information carried by the AE Signature and provide improved diagnostics.

To determine control structures and possible power quality issues, the dynamic torque generated by the blades of a wind turbine must be represented. This paper presents an analytical formulation of

Vibration-based Condition Monitoring: Industrial, Aerospace and Automotive Applications

Explaining complex ideas in an easy to understand way, Vibration-based Condition Monitoring provides a comprehensive survey of the application of vibration analysis to the condition monitoring of

Condition monitoring architecture: To reduce total cost of ownership

A CMS architecture which reduces the total cost of ownership by reducing hardware cost (MEMS based sensor and local processing), reducing IT cost by deploying to a compute cloud, and reducing the cost of knowledge creation by incorporating advanced digital signal processing and decision support algorithms into the CMS application is presented.

A Review of Time Synchronous Average Algorithms

This paper addresses four topics in relation to the TSA performance characteristics, quantifying the ergodicity/noise reduction as a function of the number of revolutions in the TSA and showing that noise reduction is 1/sqrt(number of revolutions).
