Improvement of Power factor

We can improve power factor by :

• Static capacitors.
• Synchronous condensor.
• Use FACTS.

Static capacitors:

are used to generate reactive power and to improve the power factor. Capacitors compensate the reactive power absorbed by inductive loads.

Synchronous condenser:

Synchronous motor without load is also used to improve power factor.

Use FACTS: 

"FLEXIBLE AC TRANSMISSION SYSTEM"  devices are used to improve power factor.
