| Résumé: | The demand for oil and gas increases every year due to the immense development the
world is currently undergoing. Oil and gas operating companies need to come up with
innovative and optimistic design for the facilities to extract and deliver the oil and gas
from the earth’s crust, processing and delivering to the user. Thus, having a reliable and
robust power system design for the compressor station is vital. The main objective of this
research is to perform load flow, largest motor starting, short circuit studies and relay
protection coordination for the compressor station. The studies are performed using
ETAP Power Systems Software. Based on the load flow studies performed, all the
equipment steady state loading and voltage deviation is within the acceptable range. The
largest motor starting study is performed to investigate and to confirm should the direct
on-line method is practical for starting the largest motor to the system transient
performance. From the motor starting study performed, a direct online starting method is
sufficient to start the largest motor and the voltage drop occurs within the standard range.
The short circuit studies were able to specify the maximum short circuit current all the
high voltage and low voltage equipment in the system are required to withstand during a
fault prior to tripping by the protection system. The final studies is the relay
discrimination studies that showing how the sequence of response by relays accordingly
to the desired setting. The results of the studies performed will be useful for electrical
consultants to design an optimized, reliable and robust electrical network on compressor
station.
