The Voltage Stability Enhancement of IEEE 14bus System Using the Facts Controller Device

B. Prajapati, A. Kashiv, Dr. A. Mahar


This paper is concerned with the problem of voltage stability. The paper analyses the usefulness of voltage ratio proximity indicator to identify weakest bus in a system for improving voltage stability. The results are carried out over a wide range of load. Test results for the IEEE 14 bus 20 line System are presented. Result obtained from this technique shows that suggested indicator can provide useful information at any operating point bandit is reliable and capable to identify weakest bus and facts controller device used for improving voltage stability.
To analyses the effect of facts device voltage stability shunt capacitor is connected to weakest bus. And result will be obtained for it.
Keywords: Voltage Ratio indicator (VRI), Voltage stability, Mat lab.
