A Novel Method of Power Flow Control for the Compensation of Harmonics and Unbalanced Currents in Electric Railway Systems
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2016, Vol 4, Issue 7
Abstract
This paper presents a novel method of power flow compensation of broad filtering and unbalance return system for electric traction systems using fuzzy logic controller. For a balanced three-phase three- wire system, the planned technique is able to control the power flow switch among the grid and the load so that the immediate compound power is maintained steady. As a result any nonlinear unbalanced load is seen by the three-phase sup- ply as a balanced linear load. The planned filter is evaluated on power substations with open delta (V-V) and Scott transformer feeders and for two-level and dual-converter in the power stage. The system has been simulated. The outcome from simulation tests shows the fuzzy logic controller advantages and the applicability comparedwith the direct control based algorithm inElectricrailway systems.
