I. INTRODUCTION
HE STATCOM, which is a short name for Static
Synchronous Compensator, is a second generation
FACTS or Flexible AC Transmission System device. It is
classified as a shunt compensator.
Basic STATCOM circuit (Fig. 1) consists of a voltage
source converter (VSC) and a dc storage capacitor. The VSC
converts ac voltages ( VA,VB,VC) to dc voltage level on the dc
side (UDC). The capacitor voltage can be ad..................[:=> Show Contents <=:]

solution. The ratings of commercial DFIG-based
wind turbines now reach 5MW .
The converter-controlled DFIG, STATCOM and LCC
HVDC have all been well studied as separate components. In
, the overall power system concept and possible control
paradigms have been described, but these studies have not
included system analysis or a formal procedure of control
system design. A detailed mathematical study of the system

Transient Disturbance
Transient disturbances are undesirable momentary deviation of the supply voltage or load current and caused by the injection of energy by switching or by lightning.

Transients are classified in two categories Impulsive and oscillatory
