A Review on Reactive Power Compensation Techniques using FACTS Devices

The paper describes a study of various techniques of reactive power compensation needed by any power system network using FACTS device. It is better solution to any power transmission related problems in today's world to implement FACTS device for either lagging or leading behavior of power system network. In this paper we study the shunt operation of FACTS controller, the STATCOM and how it helps in the better utilization of a network operating under normal conditions. Firstly, a literature review of many papers related to FACTS and STATCOM, along with reactive power control are to be considered and analyze. The study of STATCOM and its principles of operation and control, including phase angle control and PWM techniques, are carried out. However, these are very useful in determining the behavior of the system under a fault condition.
