Question

Reactive power compensation in feeders leads to:
1. expensive voltage regulators
2. improved voltage profile
3. negative and zero sequence currents
4. poor voltage profile

Answer 1

Correct Answer - Option 2 : improved voltage profile

Reactive power compensation in the feeder uses a shunt compensator in the middle of the line (generally).

• It can maintain the voltage V_S and V_R equal irrespective of the direction of power flow.
• It ideally doubles the power handling capacity of the transmission line, improves the steady-state performance, damps out the transient oscillations.
• It also improves the power factor and maintains a good voltage profile.
