Advantage of FACTS Controller
• To increase the power transfer capability of the transmission networks.
• Provide direct control of the power flow along specified transmission routes.
• Control power flow as directed, to conform with specified transmission corridors.
• Improve net transfer reliability
• Increase power transmission without adding new transmission line.
• The costs of transmission are minimized.
• Smooth stable condition, and dynamic control.
• Power oscillations actively dampen.
• Boost machine reliability and stress management.
• Give new generation sitting more flexibility.
• Energy flow control in transmission corridors by a line control
• Impedance, angle and voltage ;
• Optimum power flow for certain objectives
• Increase the charging capacity of lines to their thermal efficiency,
