Diagnosing wear faults - High-throughput screening of wind-turbine gearbox samples using the LaserNet 230 and automatic sample processor (ASP).
The major issue for premature failure in wind-turbine gearboxes is bearing failure, which leads to gearbox failure. A wind-turbine gearbox will not survive if the oil is not clean and especially if the hard ferrous particles are not removed from around the bearings. The LaserNet 230 particle counter and ferrous debris monitor has been shown to be an excellent analytical tool for end users to ...

Engineering Innovation into Driveline Design
Introduction: thinking differently What is innovation? How can you harness innovation in practical ways to support your business goals? In the driveline industry and for engineering in general, “innovation” is often synonymous with the use of new or novel technologies/methods to achieve design and development goals - and ultimately deliver a higher quality product - in faster, more ...

Robust vector control strategy for variable speed wind turbines
The efficiency of the wind power conversions systems can be greatly improved using an appropriate control algorithm. In this work, a robust control for variable speed wind power generation that incorporates a doubly feed induction generator is described. The electrical systems incorporate a wound rotor induction machine with back–to–back three phase power converter bridges between its rotor and ...

Modelling and control of a variable speed wind turbine driving doubly fed induction generator using three–level PWM converter
The aim of this researcher is to develop a complete wind central model driven doubly fed induction generator (DFIG) which feeds an AC power grid. For that, two–pulse width modulated (PWM) voltage converters are connected back to back between the rotor terminals of DFIG and the utility grid via a common DC link, in there, our contribution will appear in the utilisation of three levels voltage ...

Vector control of current regulated inverter connected to grid for wind energy applications
Connecting variable speed wind turbine connected to the grid requires a proper control of the inverter to improve the power quality for the system. The vector control of an inverter connected to the grid is presented. The proposed control technique implies a hysteresis current controller in the inner loop. The complete control system has been developed, analysed, and validated by simulation ...

Variable susceptance excitation control for dynamic performance improvement of a stand-alone wind turbine induction generator system
Isolated wind farms employ simple squirrel cage induction generators driven by variable speed wind turbines. Lacking control capability, such generation can contribute very little to network support. Wind turbines mostly do not take part in voltage and frequency control and if a disturbance occurs, the turbines may be disconnected and reconnected when normal operation has been resumed. From ...

Wind farms benefting the region
Wind farms as close as Benton and White counties—and others around the world—are boosting Tippecanoe County’s economy by at least $20 million a year, reports Jody Hamilton, director of economic development for Greater Lafayette Commerce. “From land title searches to construction labor and turbine components, businesses in Greater Lafayette are enjoying new revenues, and that figure doesn’t ...
