Main objective of the paper is to study the impact of SVC on stability and enhancing the power quality for a real time industrial system. Modified RK method is used for transient stability analysis and detailed frequency modeling is used for harmonic analysis. Real time system of 3.5 MTPA Steel plant at Raichur in Karnaraka, India with Electric Arc Furnace and Laddle Refining Furnace are considered for study. ETAP 12.6 software is used to simulate both transients and harmonic analysis. Harmonic study is performed with sinusoidal source non linear loads and Non sinusioidal source non linear loads. SVC performance when the non sinusoidal source is also verified to have the practical meaning. For Transient stability enhancement the controller tuning fault at 11V and 33KV bus is verified.
