Abstract

In Locomotives 70% of all railways was fully equipped with the new technologies especially to drive the Induction motor. In VSI the variable frequency of 0 to 160 Hz was at present used in the locomotive with short circuiting problem. In this paper It deals a new technologies for locomotive especially for WAP-7D.Earlier stage in locomotive the converter was designed with GTO and microcontroller based techniques where many drawbacks in that system. In this paper the new proposed 21 level multilevel inverter using regenerative braking was compared with the closed loop using ANFIS and PID. The speed of the three phase squirrel cage induction was controlled and the total harmonic distortion was compared by the OL and CL system in this paper. SPWM technique was carried out to reduce the THD for the proposed system. The simulation was carried out for the OL and CL system using MATLAB simulink.
