Wind turbine controlling of the future
Higher, more robust, more reliable: Parallel to the growing requirements for wind turbines, the requirements for monitoring sensors grow as well. But how can wind sensor manufacturers fulfil these wishes? And how should a future wind sensors look like? After analysing the current conditions and trends on the wind energy market, our CEO Klaus Hirzel compiled a wish list for future wind sensors. ...

Ultrasonic wind sensor for smart wind turbine control - Polaris / USA - Case Study
The American wind turbine manufacturer Polaris trusts for their wind turbine applications anemometers from Lufft. Over 50 wind turbines have already been equipped with our ultrasonic anemometers Ventus-UMB and V200A-UMB. Crucial in these applications is a high degree of precision and a long, maintenance-free useful life. In addition, controlling of the turbine complex requires a high frequency of ...

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 ...

Data–driven modelling, control, and fault detection of wind turbine systems
In this paper, data–driven system modelling, control, and fault detection technique for wind turbine systems are researched. The developed algorithm is to recursively update system parameters using predictor–based system identification (SID) technique. Updated system parameters are used to design subspace predictive controller for wind turbine systems with constraint on pitch angle and generator ...

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 ...

Small wind turbine emulator with armature controlled separately excited DC motor via analogue electronic circuit
In this paper, a small wind turbine emulator (WTE) using separately excited DC motor is modelled, designed, simulated, implemented and tested. A 1 HP separately excited DC motor is used to emulate the characteristics of the rotor of small wind turbine. The DC motor is driven by a thyristor bridge with closed–loop cascaded PI controller for armature control. A separately excited DC generator with ...

Optimal control of matrix converter based WECS for performance and stability enhancement at low wind speeds
In this paper, optimal control of new wind energy conversion scheme where four-leg improved matrix converter (MC) is used for performance and stability enhancement, particularly for sites where most of the time low wind speeds prevails, has been explained. The power factor at the interface with the grid is controlled by the MC to ensure purely active power injection into the grid for optimal ...

A combined electro-mechanical control technique for dynamic voltage regulation of a stand-alone wind turbine generator
This paper introduces a computer-based model and dynamic simulation of a combined electro-mechanical control technique for a stand-alone wind turbine generator system. The presented combined control technique consists of three closed loops for speed regulation, nacelle alignment and dynamic load voltage regulation. Speed regulation is achieved by adjusting the pitch angle of the turbine blades. ...

Dust control solutions for wind turbine rotor blade manufacturing
Wind turbine rotor blade manufacturing involves incessant grinding passes that create large quantities of particulate and require innovative dust control solutions. Rotor blades usually range between 30 and 60 meters long. Made by layering thousands of thin filaments impregnated with epoxy resin, the rotor blades have to be reduced to the proper dimensions and prepared to accept the next layer ...

Measuring Offshore Wind Resources
To select the right offshore wind site, estimate the future energy output of a wind farm, and determine the best layout for the turbines, project developers must conduct wind resource assessment (WRA) campaigns on site. This is a critical phase of the successful development of wind farms. WRA campaigns on terrestrial sites have traditionally been performed using meteorological towers equipped ...
