تعد منطقة قطينة في محافظة حمص من أكثر المناطق في سورية ملائمةً لإنشاء نظام تحويل طاقة ريحي. يمكن ربط هذا النظام مع الشبكة الكهربائية السورية بدون تكاليف كبيرة نظراً لقرب المنطقة من الشبكة. لكن تغير سرعة الرياح، الدائم و غير المستقر، يؤدي إلى ظهور جهود مختلفة في التردد و المطال على خرج النظام غير مطابقة لجهد و تردد الشبكة الكهربائية السورية مما يعيق عملية الربط. يهدف هذا البحث إلى تصميم نظام تحويل طاقة ريحي ملائم لمنطقة قطينة و التحكم به بحيث نحصل دائماً على جهد و تردد ثابتين و مطابقين لجهد و تردد الشبكة الكهربائية السورية لتسهيل عملية ربطه مع الشبكة. و ذلك عند أي سرعة رياح على دخل النظام الريحي و من أجل أي حمولة على خرجه. تم اختيار العنفة الملائمة و المولد الملائم للمنطقة اعتماداً على بارامترات تابع احتمالي رياضي، يسمى تابع وايبل (Weibull Function). بعد ذلك تم تصميم نظام التحكم المناسب لمطابقة خرج النظام الريحي من جهد و تردد مع جهد و تردد الشبكة الكهربائية السورية. حيث تم التحكم بالمقطع الرافع - الخافض باستخدام متحكم تناسبي تكاملي (Proportional Integral) بحيث نحصل دائماً على جهد خرج مستمر ثابت مقداره. أما عملية التحكم بالقالبة فقد تمت باستخدام حلقتي، حلقة خارجية للتحكم بالجهد و حلقة داخلية للتحكم بالتيار. و ذلك من أجل الحصول على جهد جيبي ثلاثي الطور قيمته الفعالة الطورية (220V) و تردده (50 Hz). للتحقق من صحة و صلاحية و فعالية النظام المقترح، تمت نمذجته ببرنامج MATLAB و محاكاة عمله. و قد أظهرت نتائج المحاكاة إمكانية الحصول على جهد ذو مطال و تردد ثابتين لا يتغيران بتغير سرعة الرياح أو الحمولة.
Kouttina is one of the most proper areas in Syria for building wind energy conversion system. This system could be coupled with Syrian electrical grid without expensive cost because of nearing from the grid. But the permanent changes of wind speed with no stable mode, cause different amplitude and frequency voltages differ from Syrian electrical grid amplitude and frequency. The goal of this research is to design proper wind energy conversion system for Kouttina area and control it, therefore we always obtain constant amplitude and frequency voltages equal to those of Syrian electrical grid for any wind speed and load. The proper wind turbine with its generator was chosen depending on parameters of probability mathematic function, called Wiebull Function. After that the proper control system was designed for equaling the amplitude and frequency of wind energy conversion system output with those of Syrian electrical grid. The buck -boost converter was controlled by proportional integral (PI) controller to always have DC output voltage equal to (622V). While the inverter controller was achieved by using two PI control loops, the outer loop for voltage control and the inner loop for current control. Though, three phase voltage with RMS phaser value of (220V) and frequency value of (50Hz) is achieved. To validated the correctness and effectiveness of the proposed system, it was modeled using MATLAB program. The results showed the system ability of obtaining voltage with constant amplitude and frequency and this values do not change with wind speed or load changes.

Electric energy is very important for sustaining the good life on the planet's surface, especially since civilization has become associated with this type of energy. Solar photovoltaic (PV) is one of the most suitable applications for converting sunl
ight into electrical energy. The appropriate use of solar energy is an important topic for reducing dependence on fossil energy sources that are used to generate electricity, and thus reducing the emissions of greenhouse gases on the planet's surface. Globally, because of environmental conditions, other methods of generating energy being searched for that are less harmful than traditional methods, which rely on a large percentage of them on generating stations that run on fossil fuels. This research discusses electrical power generation using solar energy cells and the effect of these cells on the Syrian electrical grid so that a study of a solar energy farm project provides the data required when working on implementing such a project, and these data are voltage control, load flow, total harmonic distortion coefficient levels. To implement such a project, the model must be designed and we chose the ETAP program for that.
Solar and wind energy is considered as one of the best renewable energy resources
because it Available and economical . We can take advantage of these two resources of
renewable energy in Katina area in Homs for designing and building a bilateral r
esources
(solar-wind) electric power system, depending on the daily bending of the wind speed and
the solar radiation intensity in the studied area.
This research studies the design of a hybrid wind and solar system by selecting its
components that available in the local market in terms of their nominal, technical
specifications, based on the technical and economic studies and the corresponding
international standards. The obtained results showed that we have approximately (1246.7
Kw/Year) surplus during the year for the benefit of consumers, which makes the system
economically feasible for investment, as explained in research needs an additional resource
to feed the load and charge the energy-savings with (3360.2 w/day) that constituting (50.4
%) of the volume of the load in addition to the practical results provides a theoretical
database, whether for the researcher or the investor in the field of renewable energies,
particularly in terms of the efficiency of selecting the system’s components.
This paper presents a three phase shunt Active Power Filter (APF) for power quality
improvements in terms of harmonics compensation. The compensation process is based on
measure non-liner load currents and Active Filter currents, and then extract t
he references
from measured currents. Measured currents are then transferred from abc frame to d-q
reference frame. A Synchronous Proportional Integral controller (Synchronous PI
controller) is used. The control signals then drive the Pulse Width Modulation (PWM)
routine, where its output controls the Voltage Source Inverter (VSI) switching devices. The
performance of the Active Filter and the Synchronous PI controller is validated though the
simulink results in MATLAB environment.
