The doubly fed induction generator (DFIG) systems feature a significant amount of free power capacity that may be used for reactive adjustment when they are put into practical use. This change, which is occasionally overlooked, one. Using DFIG wind turbines (WT), this paper explored strategies reducing and using power. In order to investigate the characteristic how it regulated in systems, math...

Wind turbines' participation in frequency response is known to improve the stability of power systems, but it can also have a negative impact on fatigue load wind turbines. The objective this paper investigate effect loads experienced by various components turbine, including low-speed shaft, tower, and blade. To achieve goal, authors develop model variable speed horizontal-axis turbine based do...

Power quality issues associated with the fixed speed wind farm substation located at Coimbatore district are investigated as the wind generators are tripping frequently. The investigations are carried out using two power quality analyzers, Fluke 435 and Dranetz PX5.8, with one of them connected at group control breaker of the 110 kV feeder and the other at the selected 0.69 kV generator busbar ...

This paper deals with a protection and control strategy to enhance the low voltage ride through capability of a wind turbine driven doubly fed induction generator (DFIG). As the wind power penetration continues to increase, wind turbines are required to provide Low Voltage Ride-Through (LVRT) capability. Crowbars are commonly used to protect the power converters during voltage dips and their ma...

<p>The work presents the dual-rotor wind energy conversion system (DRWECS) with a direct driven doubly-fed induction generator (DFIG). The consists of turbine (DRWT) DFIG, grid side converter (GSC), and machine (MSC). To command MSC, power (DPC) based on genetic algorithm (GA) classical pulse width modulation (PWM) has been applied. achieve maximum from DRWT, powe point tracking (MPPT) te...

A wind power system differs from a conventional power system. In a conventional power plant, the operator can control the plant's output. The output of a wind farm cannot be controlled because the output fluctuates with the wind. In this study, we investigated only the fixed-frequency induction generator, often used with wind turbines. We adopted the worst-case scenario and conducted a per-phas...

Wind energy conversion systems are very different in nature from conventional generators. Therefore dynamic studies must be addressed in order to integrate wind power into the power system. Angular stability assessment of wind power generator is one of main issues in power system security and operation. The angular stability for the wind power generator is determined by its corresponding Critic...

The main objective of the paper is to develop a probabilistic model for capacity factor estimation for a wind turbine located in a specific area, model based on the output power distribution of wind turbine. This model was applied for a wind turbine located to a region in the North-East of Romania, the model results being validate with results from Monte-Carlo simulation. Finally, the model was...
