Sag / Swell and Harmonic Reduction in Transmission Line Using D-Facts Device DPFC
Journal Title: IOSR Journals (IOSR Journal of Electrical and Electronics Engineering) - Year 2018, Vol 13, Issue 2
Abstract
A new control scheme to improve and maintain the power quality of an electrical power system is distributed power flow controller (DPFC).The DPFC is derived from the unified power-flow controller (UPFC). The DPFC can be considered as a UPFC with an eliminated common dc link. The active power exchange between the shunt and series converters which is through the common dc link in the UPFC is now through the transmission lines at the third-harmonic frequency. In DPFC the common link between shunt converter and series converter is eliminated and instead of three phase series converter several single phase distributed series converters are modeled. The large number of series converters provides redundancy, thereby increasing the system reliability. Nowadays there is growth in Electricity demand and increase in non-linear load causes the major power quality problems like harmonics voltage sag and swell in power grid. Experimental results are carried out in MATLAB/Simulink.
