Pemodelan Dan Analisis Kompensator Seri Menggunakan Thyristor Untuk Sistem Daya Listrik :
ABSTRACT
Along with the growth of society and technological improvements, the
demand for electricity continues to increase. However, the development of the
electric power system is not sufficient to supply the needed electrical energy. For
this reason, it is necessary to regulate and manage a good electricity distribution
system so that the current growth of community needs is met and has a high enough
reliability. The installation failure in the electric power system cannot be avoided
due to the long transmission distance. This has a major effect on the flow of power
in electric power transmission resulting in a decrease in voltage and loss of
electrical power. One of the ways to overcome voltage stability and improve the
reliability of the electrical power system is to use a Flexible Alternating Current
Transmission System (FACTS). One of the FACTS devices is the Thyristor
Controlled Series Compensator (TCSC). The TCSC is installed in series with the
transmission line and is used to increase the power capabilities of the transmission
line. Regulating the reactance of the transmission line can be done by controlling
the reactance of the TCSC so that the power flowing can be increased. After
conducting a power flow study using the MATLAB 2016a PSAT toolbox software,
it was found that the voltage on the Bangkinang bus was 0.9868 p.u (148.02 kV)
and on the Garuda Sakti bus was 0.9637 p.u (144.55 kV). After installing the TCSC
on the Riau 150 kV transmission system, the TCSC was installed on the Garuda
Sakti transmission line - Balai Pungut. The installed TCSC rating is 25 Mvar. The
value of the alpha parameter is 0.2 and (-0.8) radians. After installing the TCSC,
voltage stability the Bangkinang bus and the Garuda Sakti bus increased to 0.99008
p.u (148.512 kV) and 0.97693 p.u (146.535 kV). The percentage increase is 0.4%
on the Bangkinang bus, 1.15% on the Garuda Sakti bus, the average stress on the
object of research has increased by 1.15%.
