Analysis and Performance Improvement of Induction Motor drive for Traction Application

Abstract

Induction motor is widely used in many fields due to its simple structure, well-grounded operation, and small capacity of precise power. The conventional traction motor drives have been observed experimentally that there is a presence of speed deviation and torque ripples. Therefore, it becomes much essential to verify the control performance of the system by including its non- linear characteristics. To overcome the disadvantages mentioned above, the parameters of an induction motor which is most efficient will be estimated. The induction motor is dynamically modelled using this estimated parameter. So the proposed system focuses on improving the performance of traction motor drive by implementing the multilevel inverter fed sensor less induction motor using modified model reference adaptive system and compared with conventional model reference system based voltage source inverter. The simulation and hardware results will be realized for proposed system and compared with conventional system.

Economic evaluation of induction motor based on motor’s nameplate data and initial cost

“…The elimination of ∆PF&W and ∆Pstray in (6) distributed their values proportionally between ∆PNL and ∆PLL, applying linearization yields that the percentage of the ∆PNL and ∆PLL proportional to the ∆P are approximately 28% 72%, respectively. Then, the percentage value of ∆PNL and ∆PLL to the ∆P becomes respectively as in ( 9) and (10).…”

“…However, a rotor frame was developed to enhance the efficiency of IM in terms of cost savings and emission reduction [9]. The finite element technique is used to evaluate the IM design's performance considering the drive control and torque-speed range [10]. The optimal design of the IM considering economic evaluation and efficiency was introduced [11].…”
