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.
Recent developments in the area of HVDC and FACTS are dominated by two new technology trends.
This first is the introduction of ultra high dc voltage systems for bulk power transmission, and the second
is the increased application of voltage-source
d converters (VSC) in HVDC and FACTS schemes.
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 as
sociated 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.
