Why FACTS Devices ?

• Greater power control.
• Secure loading of transmission lines.
• Greater ability to transfer the power.
• Prevention of cascading outages.
• Damping of power system oscillation.

Application of STATCOM

• Act as an Active Filter .
• Controls the reactive Power with voltage support.
• Faster response to import power.
• Faster voltage regulation at load.
• High performance during low voltage condition.

SVC
14
Application of SVC

• Provide fast acting reactive power.
• Reactive power directly proportional to bus
  voltage.
• Faster response time.
• Enhance the transient stability margin.
• Enhance Voltage.
• Reduce voltage variation.
• Voltage control, Frequency Stabilization.

15
SVC and TCSC

• Both builds a module ( Fixed Parallel capacitance
  Thyristor controlled reactor).
• Reduce congestions and power overload in lines.
• SVC injecting or absorbing reactive power in
  order to control the voltage.
• TCSC modify the line impedance and control the
  power flow.

UPFC
17
Application of UPFC

• Simultaneously control 3 parameters(i.e.,
  voltage, impedance, phase angle) and this unique
  capability is signified by the adjective
  unified in its name.
• It controls the voltage regulation, phase
  shifting, Series compensation.
• It control both the real and reactive power.
• Power flow control under power system oscillation
  and transmission line faults.
