Voltage Flicker Mitigation by FACTS Devices

Voltage Flicker Mitigation by FACTS Devices

This voltage flicker occurs due to non linear loads. A
three phase four wire inverter system is consider to compensate
the voltage flicker.
The three phase four wire inverter can perform multi
functions such as : 1) it transfers the power to the main line from
DC link , and 2) it acts as shunt Active Power Filter to mitigate
reactive power demand, unbalance current, harmonic content in
load current, and neutral current at load. Inverter can perform
these functions individually or simultaneously.
