Types of FACTS Controller

1. Series Controller 2. Shunt Controller 3. Combined Series-Series Controller 4. Combined Series-Shunt Controller

Types of FACTS Controller

1. Series Controller - The series controller is used to introduce or inject voltage in series with the line voltage.

2. Shunt Controller

This type of device is used to inject current into the power system at the end of connection.

3. Combined Series-Series Controller

In this controller, combined the series-series controller with the line. It can transfer real power with lines a via DC power link.

4. Combined Series-Shunt Controller

This type of controller is used to introduce voltage in parallel using the shunt controller.
