Improvement of Power System Stability Using Static Var Compansator with Controller
Journal Title: International Journal of Advanced Research in Computer Engineering & Technology(IJARCET) - Year 2012, Vol 1, Issue 9
Abstract
This paper presents some new & different types of SVC controller & compare their performance for different types of faults during transient conditions to improve the the stability of multi-machine large scale power system. This paper contributes to the improvement of transient stability of multi- machines power system by using different types of SVC controllers i.e. P.O.D, P.I, P.I.D & generic controllers. The system response was simulated and evaluated during single and three phase line to line faults applied to the terminals. Phasor simulation results, due to single and three-phase faults under different loading conditions were performed to demonstrate the robustness and effectiveness of the developed controller in terms of fast response and less settling time. This work is presented to improve the voltage stability by using SVC without and with different types of controller & compare their performance to enhance the stability of power system. Simulation results show that, If no controllers are applied in SVC, then the rating of SVC becomes very large, system stability times becomes large, On the other hand, If controllers are used then small rating SVC can improve system stability within very smallest possible time. So, SVC with controllers can improve power system stability effectively.
