يقسم هذا البحث إلى قسمين نظري و عملي. يوضح القسم النظري أهمية الربط الكهربائي للمحافظة على استقرار التردد, حيث ذكرت أهم الفوائد الاقتصادية و الفنية التي حققها مشروع الربط الثماني في مجال الاستقرار للشبكة الكهربائية بشكل عام و استقرار التردد بشكل خاص و المعوقات و الإجراءات المتبعة لتذليلها. و يعرض القس العملي عدة تجارب عمى الشبكة السورية لسنة 2011 باستخدام برنامج PSS/E, و الاعتماد على هذا البرنامج بعد مطابقة نتائجه مع النتائج الواقعية من خلال , تطبيق عدة حوادث تعتيم حصلت في الشبكة السورية, حيث تم التركيز في تجارب هذا البحث على أهمية الاحتياطي الدوار و الربط الكهربائي و فصل الحمولات الكهربائية باستخدام الحمايات الترددية للمحافظة على استقرار التردد في الشبكة الكهربائية السورية, و تجنب هبوطه إلى قيم غير مرغوب بها.
This research is divided into theoretical and practical sections. The theoretical section clarifies the importance of electrical interconnection in frequency stability, which reports the most important technical and economic benefits achieved for the electrical network stability in general and frequency stability by the (EIJLLPST) project. The practical section will introducea number of simulation on the Syrian network for the year 2011 using the PSS/E, and rely on this program after comparing the results with the results of real situations, through the application of several incidents of blackout occurred in the Syrian network (and archived of frequency when they occur) Where the experienced of this research was focus on the importance of the spinning reserve, electrical interconnection and the separation of electrical loads using underfrequency rely To maintain the stability of electrical grid frequency in Syria ,and to avoid falling into undesirable values of frequency.

This study aims to analyze the effect of the wind farms on frequency stability of the electrical power network, and the description of the performance of Syrian Electrical Power System with integration of
wind farms in several regions in Syria (Al-Q
uenetera – Al-Hejana - Ghabagheb) through the evaluation of frequency stability of the power system and the Critical Clearing Time (CCT).
The effect of wind farms on the frequency behavior of Syrian network and factors related will be investigated such as generation technology by replacing the power-generated source by two main types
of induction generators, changing the location of wind farms and increasing gradually the rate of wind power.
The simulation analysis will be applied on Syrian Electrical Power System 230KV – 400KV, by using program NEPLAN, which gives access to an extensive library of grid components, and relevant wind
turbine model.
In this research the dynamic impact of the interconnection on the rotor
angle Stability for Synchronous Generators in the Syrian Network were
analyzed through the dynamic simulation of the power system and building
of equations is linear and then
use the program PSS / E (Power system
simulation)to resolve and identify determinants of the system and
determine critical fault clearing times of three-phase faults on the 400 KV
addition to identifying the angular revolving generators and thus to verify
the stability whether of its work independently within the Syrian electrical
system or as part of the five countries interconnection project.
The out-of-stability state of synchronous generator which
connected to high voltage network due to the transient
situations which lead us to disconnect the generator causes
finincial and technical problems. Therfore the purpose of this
research i
s to study the stability of synchronous generator
working which connected to high voltage network through the
transient situation.This research present the posibilty of
returning the synchronous generator to synchronous-steadystate
at the late time of the transient state when the load
angle is in the out-of-stability zone through controling the
rotor-excitation and increasing the generator’s electric motive
force.This lead to increase the generator’s maximum power
and to increase the generator’s stability-torque which lead to
return the synchronous generator to synchronous-steadystate
without need of discconecting it from network.Then put
the mathmatical model.
Due to the large and rapid increase in the demand for electricity and the gradual decline of
non-renewable sources of energy (fossil fuels, etc.), the performance of electrical systems
has to be developed so the use of distributed generation and it
s connection with the main
networks is one of these methods but this linkage causes some problems like changing in
electrical voltage.
In this research a radial electric distribution system was simulated and studied the effect of
distributed generation on electrical voltage stability -in static and dynamic state-and its
effect when the generator is synchronous or induction.
Medical emergencies could occur during the practice of dentistry. A dentist
must be prepared to recognize and manage of any potential emergency situation. The purposes of the
study were to determine the occurrence of medical emergencies in Damascus dental clinics, and to assess
the way patients' medical history is taken.
