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.

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.

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.

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.
