Critical review
تُعد هذه الدراسة خطوة مهمة في مجال تحسين أداء العنفات الريحية، إلا أن هناك بعض النقاط التي يمكن تحسينها. أولاً، كان من الأفضل تضمين تحليل اقتصادي لتكلفة تطبيق تقنية الامتصاص مقارنة بالفوائد الطاقوية المحققة. ثانيًا، يمكن توسيع نطاق الدراسة ليشمل أنواعًا مختلفة من العنفات الريحية وأحجامها المختلفة لتعميم النتائج. ثالثًا، لم يتم التطرق بشكل كافٍ إلى تأثير الظروف الجوية المتغيرة على فعالية تقنية الامتصاص. وأخيرًا، كان من الممكن استخدام تقنيات محاكاة متقدمة لتحليل الأداء بدلاً من الاعتماد فقط على التجارب الميدانية.

This research shows that the design of wind turbine blade for the best production of energy produces a turbine with a problem of start-up. The study focused on ways to improve the process of the small wind turbine start-up at the low wind speed w ith the stability of the pitch blade angle, and study the behavior of the turbine during the stage of angular acceleration after the start-up until the turbine reaches the speed of rotation that enable it to produce the energy.
Our research includes the transmission mechanism of the wind turbine and the calculation of losses, such as loss of mechanical ventilation and friction loss and the loss of lubrication between the gear teeth design. Aims and access to high reliabili ty work and thus obtain high efficiency and taking advantage of electronic programs, We observed that each type of previous losses have an impact on the overall loss of Gearbox, Depending on the working conditions, For example, at low speeds, loss of friction between the teeth is a great percentage of the total loss, And thus controls the overall efficiency of the transport system, while at high speeds noticed this low percentage of loss, while the loss of lubrication and ventilation rate rose.
The aim of this paper is to investigate the overlap between lower atmospheric boundary layer and real wind turbine wake which installed not far from ground surface, Here we adopted rotating actuator-disk model (RADM) as a complex model of 3D actuator -disk model, virtual blade modeling (VBM) and tip loss correction, in order to get more reliability and satisfied result. Wind turbines have grown significantly in size over the last years and, it generally placed in an atmospheric boundary layer, then the assumption of uniform wind velocity cannot be valid. The lower part of atmospheric boundary layer has a high level of turbulence intensity and great velocity gradients, then when wind turbine placed in these conditions, a high rate of fluctuation will occur subsequently power losses in wind farms, and change wake turbulence character which affects the flow-induced dynamic loads on downwind turbines.
reliance on new and renewable sources of energy has grown in order to obtain electric power without the use of traditional fossil fuel sources. And thus solve the problems of the global energy crisis and also maintain a clean environment, through the fight against the dangers of global warming and its negative results Wind power is considered as one of the most important of these alternative energies. We will work in this research in order to be able to control wind turbine with variable speed through pitch angle control in order to organize power and control the rotational speed in order to make the power ideal. Where we will be using a fuzzy controller to control pitch angle instead of the traditional controllers, which is expected to improve system response and provide ease in the application and modification and reduction in the cost. By reference study we came to the result showing that most previous studies in advanced wind energy systems have addressed to control wind turbine using conventional controllers from PI or PID type. Show we have the problem of the need to know the exact mathematical model of the system. Where traditional controllers of wind turbines that operate at variable speed are based on mathematical models which may be complex and non-linear and neglect often physical phenomena, for example, magnetic saturation which leads to complexity in the calculation and unexpected performance of the driven system. The proposed research aims to provide a complete study through modeling and simulation using the Matlab about the use of fuzzy controller to control the wind turbine where traditional controllers of type PI will be designed to control the pitch angle and to control the rotational speed and fuzzy PI controllers to control the pitch angle. Results will be get and discussed and conclusion will be extracted from them. Research Results showed that the fuzzy control improves transient state behavior, but the steady-state behavior is better controlled when we use PI controller. So and based on the result we got, the PI controller can't be replaced actually with the fuzzy controller.
It is the automatic control engineering knowledge forum, as it should monitor and control the variables that interact in all industrial processes to perform functions equipment installations constructed for her. The automatic control system techno logy has a big role in easing the burden of daily life, and make them more luxury. automatic control applications in most appliances, such as: air conditioning and stoves, washing machines, etc.Automated control concepts has been used in various areas of knowledge such as biology, economics, sociology, medicine and education .
