Abstract

Nowadays it is more important to design energy resourceful and economical railway system by decreasing the power losses and consumption of fuel which is slightly implemented using 500 kVA HOG (Head On Generation) converter which can take input electrical energy from 25 kV overhead wire via loco transformer. This paper explains the BBO (Biogeography Based Optimization) approach for 500 kVA HOG converter connected to locomotives. The optimization of specific lower order harmonics is carried out using harmonics of the same order and magnitude but opposite in phase. The selective switching angles for 180 and 120 are calculated offline using the BBO soft computing technique and stored in the microcontroller memory for execution. Simulation and analytical formulation data agree well. The THD (Total harmonic distortion) in output is found within the specified limit.
