Application of STATCOM to mitigate voltage sag / Nur Syazwani Shafie

The main objective of this research is to analyze the capability of STATCOM to mitigate the voltage sag due to starting of induction motor. The starting period of induction motor depends upon the factors such as, motor construction, its condition and its loading condition. Typically, the starting period is about 1 sec.; therefore there is a voltage sag in the supply voltage during this period. The solutions approached for compensation of voltage sag are either shunt injection of reactive current or series injection of voltage.
