In the recent years the wind turbine industry has focused on optimising the cost of energy. One of the important factors in the achievement of this task consists of increasing the reliability of the wind turbines, which can be obtained using advanced fault detection and isolation strategies. Clearly, most faults are managed quite easily at a wind turbine control level. However, some faults are ...

Remote sensing techniques like LiDAR offer many novel applications to the wind energy community, e.g. fast and accurate measurements of inflow and wake wind fields from the turbine nacelle. The prospects of such a new technique are evaluated with a software tool simulating a nacelle-based LiDAR system. The paper presents the implementation and application of a simulator that has been conceived ...

Wind turbine plants are complex dynamic and uncertain processes driven by stochastic inputs and disturbances, as well as different loads represented by gyroscopic, centrifugal, and gravitational forces. Moreover, as their aerodynamic models are nonlinear, both modelling and control become challenging problems. On one hand, high–fidelity simulators should contain different parameters and variabl...

This paper focuses on developing an integrated reliable and sophisticated model for ultra large wind turbines And to study the performance and analysis of vector control on large wind turbines. With the advance of power electronics technology, direct driven multi-pole radial flux PMSG (Permanent Magnet Synchronous Generator) has proven to be a good choice for wind turbines manufacturers. To stu...

Stochastic characteristics of wind power generation may lead to reliability and power quality problems in power systems. This paper presents two control schemes considering state-of-charge (SOC) in the energy storage system for the wind-turbine-generator: constant power mode and power balance mode. Because the response of energy storage system is not fast enough, estimated coming wind power is ...

A control strategy is realized which solve the problem of output power regulation of variable speed wind energy conversion systems by combining a linear control for blade pitch angle with a nonlinear H∞ torque control which mitigate the effects of external disturbances that occur at the input and output of the system. The controller exhibits better power and speed regulation when compared to cl...

-This paper presents the modeling and real-time simulation of a doubly-fed induction generator driven by a wind turbine in large power systems. The Matlab/Simulink/ SimPowerSystems software is used to develop the model for simulation of electromagnetic transients in power systems. The code generated by the Real-Time Workshop of Simulink is linked to the Hypersim digital real-time simulator. A c...

This paper deals with a realistic turbine simulator that uses a 20 kW DC motor with an independent excitation and mntmlled hy a microcompiiter. The tiirhine torque and rotation are both simnlated according to wind and load of actually driven generators with any type of rctuql loads. With the help of this simulator it is possible to develop and realise tests in electrical power plants in conditi...

To meet the growing demand for integration of renewable energy sources onto today’s power grids, many engineers from different specialized fields must be involved since various types of studies need to be conducted. The integration of distributed generation (DG) sources significantly changes the characteristics of an entire network. Such interconnection projects will require analysis of power q...

Maintaining a wind turbine and ensuring secure is not easy because of long-term exposure to the environment and high installation locations. Wind turbines need fully functional conditionmonitoring and fault diagnosis systems that prevent accidents and reduce maintenance costs. This paper presents a simulator design for fault diagnosis of wind power systems and further proposes some fault diagno...
