إحدى التحديات التي تواجه تشغيل نظم القدرة الكهربائية الكبيرة و شبكات الارتباط هي مسألة ضمان بقاء المولدات في حالة تزامن مع بعضها بعضاً بعد حدوث اضطرابات كبيرة مثل دارات القصر على خطوط النقل و قضبان التجميع و ما يرافق ذلك من عمل لنظم الحماية. حلل في هذا البحث أثر دارات القصر و مدة بقائها على استقرار المنظومة الكهربائية السورية عن طريق التمثيل الديناميكي للأعطال ثلاثية الطور على محطات التحويل مع تغيير أزمنة الفصل الحدية للأعطال على هذه المحطات. فضلاً عن ذلك حددت أزمنة الفصل الحدية للأعطال على شبكة ال 400 kV 230 و kV و قضبان التجميع لمحطات التحويل و أثر الحماية المسافية لخطوط النقل و الحماية التفاضلية لقضبان التجميع في المحافظة على استقرار المنظومة الكهربائية السورية.
One of the challenges to the operation of a large and interconnected power systems is to insure that generators will remain in synchronism with one another following large disturbances such as short circuits on transmission lines and bus bars with associated operation of protection system. In this research, the impact of short circuits and their sustained duration on Syrian power system was analyzed through the dynamic simulation of three-phase faults at substations with varying fault clearance time at these substations. In addition, critical fault clearing times on 230kV, 400kV network and substation bus bars were determined, as well as the influence of distance protection and bus bar differential protection on Syrian power system.

Efforts are being made to connect many wind farms to Syrian electrical network As of Wind turbine the
increases; their Cumulative impact on dynamic operational characteristics of power system will increase.
In this paper, the impact of constant spe
ed wind turbines utilizing squirrel cage induction generators, the
most worldwide spread nowadays, on the transient stability of Syrian power system is analyzed.
Various aspects have been considered like wind turbine penetration level, fault location on power system
overhead lines and network topology transforming.
Results of this study show that wind turbine farms planned to be connected to Syrian electrical network
will have significant impact in improving transient stability parameters (CCT,d).
As the wind turbine penetration level increases, their impact will increase, but still remain dependent on
the fault location and network topology transforming caused by double circuits of overhead lines.
This paper introduces an unconventional analytical method, namely Transient
Energy Function (TEF) method, and proves the capacity of the method. The
significant advantage of the used approach is that, integration of the swing equations
is in principle limited only to the fault-on period.
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.
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.
The contribution of our research include building an artificial neural
network in MATLAB program environment and improvement of
maximum loading point algorithm, to compute the most critical
voltage stability margin, for on-line voltage stability a
ssessment,
and a method to approximate the most critical voltage stability
margin accurately. a method to create a (ARTIFICIAL NEURAL
NETWORK) approach.
