Compensation of Voltage Swell by Using STATCOM
In power system, power quality is one of the important aspects as power quality problems are occurred due to occurrence of voltage swell, voltage sag, transient, harmonics distortion, etc. in the transmission line. Out of these, voltage swell has less predominantly occurred and creates severe impact on transmission line and sensitive devices connected
