Harmonics Reduction by Distributed Power Flow Control Using FACTs Devices in Power Supply

Nowadays, inside the group of FACTS, an additional device has been introduced named a distributed power flow controller. Unified power flow controller and DPFC has the same controller capacity DPFC is derived form of UPFC. The DPFC came into action between the shunt and series converter through the transmission line at the third harmonic frequency. DPFC uses the distributed faults ideas it’s about to use multiple small sizes single-phase converters in place of one large size three-phase as in UPFC. The performances of DPFC are based on the symmetrical three-phase fault near the load area. The Mat lab/Simulink results got to show a further developed exhibition in voltage sag mitigation and exceptional reduction in load voltage harmonics. Background: Various series and shunt FACTS devices are used to control the distributed power flow and reduced the harmonics component. Objective: DPFC technology/control strategy is discussed to control the power flow. Control: Modeling of different converters and converters is discussed for DPFC control. Result: DPFC is controlled within the permissible total harmonic distortion. Conclusion: Depending on the situation various FACTS devices need to be used for distributed power flow.
