Abstract: The instability of power transmission system in Nigeria is the concern of many individual and that is what this paper wants to address. The first stage was to analyze the effect of static synchronous compensator (STATCOM) on power transmission stability. In doing that, the three phase fault was introduced to the system at line 4-5. The Load flow simulation analysis was carried out according to IEEE 9 bus system. The power transmission system model was developed and simulated using MATLAB/SIMULINK software. The result of the simulation shows that Bus 5 was detected to violate the voltage limit of 0.95 < V< 1.05 p.u. having a voltage magnitude of 0.8875p.u. The per unit Voltage magnitude of power system with STATCOM and without STATCOM was calculated. From the result, the voltage magnitude without STATCOM was 0.8875p.u while that with STATCOM was 1.01p.u. The total active power Loss without STATCOM was 324.02MW while that with STATCOM was 322.53MW. Therefore the percentage of power system improvement is 0.23% when STATCOM was incorporated. Finally, Power transmission system improves when STATCOM was applied.
