ABSTRACT
This thesis discusses a
comprehensive study on reduction of power (active and reactive) losses in
transmission lines using a second generation FACTS device, Static Synchronous
Series Compensator (SSSC). Modem restructured power systems sometimes operate
with heavily loaded lines resulting in power losses and higher voltage
deviations, which may lead to mal-operation of power system and eventual
collapse ofthe system. This is mainly due to continuous and uncertain growth in
demand for electrical power. The research work presents a methodology to solve
the problem of power losses in the Nigerian 28 - bus power system by
incorporating Static Synchronous Series Compensator in the network using
Newton-Rahson power flow algorithm. Simulation of power flow solution without
and with the FACTS device was done using a Matlab software. The results showed
that the maximum power (active and reactive) loss in the system without SSSC
occurred in the transmission line connecting bus 17 (Jebba) to bus 23(Shiroro)
and 19.32% loss reduction was noticed on the line after the incorporation ofthe
SSSC FACTS device giving a power saving of 80.68%. The total system active and
reactive power losses before the application of SSSC was 205.183MW and
1594.683MVAR respectively. However, when the FACTS device was applied at the
weak buses the total system active and reactive power losses reduced to
144.571MW and 1136.863MVAR respectively giving a percentage loss reduction in
active and reactive power of 29.54% and 28.71% respectively resulting in a
power saving of 70.46% and 71.29%. Hence, more power was available in the network
when compared to the base case due to the installation of SSSC. Also an
improvement in the voltage magnitude at the weak buses and other buses were
noticed as they were all maintained at 1.0 PU.
