Abstract

This project will focus on developing a simulation model of variable speed, variable voltage for an induction motor drive. The main component of this system consists of a 3-phase induction motor (DL 1021) and a 3-phase ABB inverter (ACS 550-01-08A8-4). Based on the actual 3-phase induction motor (DL 1021), the parameters such as R1, X1, R2, X2 and Xm is defined using certain tests which are open and short circuit test. Using mathematical equations and MATLAB simulation, others parameter such as starting current, maximum torque and rated torque will also are defined. For variable voltage variable frequency (VVVF), the ABB inverter will play a major role. Inverter section determines the voltage level, frequency level and the current level that a motor receives in order to control the motor speed. So, the inverter section will focus on the concepts study and parameter setting of an ABB inverter. Finally, this project will develop a simple manual of variable speed control system.
