Voltage Control & Reactive Power Compensation by Statcom

The rapid development of power electronics technology provides opportunities to develop new power equipment to improve the performance of the actual power systems. During the last decade a number of control devices called Flexible AC Transmission Systems (FACTS) technology have been proposed and implemented. FACTS devices can be used for power flow control loop-flow control voltage regulation enhancement of transient stability and damping of power oscillations. FACTS devices can be used as a series controller shunt controllers or by a combination of both.
