Comparable Synchronous Condenser

Supply Variable Reactive Power And

VoltageRegulate

Principle of STATCOM

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

April 19, 202313

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 TCSCBoth 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

April 19, 202316

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.
