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.
