Abstract
Nowadays, power demand is increasing day by day and also ageing of the networks makes the system difficult for power flow control through the transmission lines. The voltage variation in transmission line should be limited which is due to the load changes; these problems are solved by using FACTS devices. A new device has been introduced called distributed power flow converter (DPFC), where distributed FACTS concept is utilized and common DC-link has been removed as present in the UPFC, and transmission line is used for the exchange of real powers between shunt and series converters. In this paper proposed carrier-less hysteresis band control (HBC) method has been used for controlling the pulses in series and shunt converters individually. The DPFC has same controllability as of the UPFC; a DPFC requires multiple numbers of one-phase series converters in place of a three-phase series converter of large rating. DPFC with single-phase series converters reduces cost and increasing reliability of the power; the whole research is implemented in MATLAB/SIMULINK.
