Abstract

This project requIres developing a speed control application for 3 phase induction motor using ABB inverter (ABB 550-01-08A8-4). It is the aiIn of this work that the application has to be developed where close loop speed control concept can be applied. The 3 phase induction motor's speed will be controlled via the feedback to the inverter. Based on calculation and comparison of data with the motor's data sheet, the necessary simulation to show the speed control is done. The ABB inve11er is also programmed based on the obtained data from the mathelnatical calculation. The ABB inverter used in this project is programmed via "DriveWindow Light 2" which is the start up and maintenance tool for Inverter ABB ACS 550 drive series. This software enables the monitoring of the actual status of the connected drive, edit and show the drive parameters. Besides that it also allows user to load the drive parameters, control the drive and also graphical monitoring of drive signals such as fi'equency, speed, torque and CUlTent. The tasks is to study the theory of 3 phase induction motor and understand the necessary calculations, design the close loop speed control application for 3 phase induction motor using ABB inverter, do simulation to compare the actual outcome through the drive, and design the electronics part for the suitable application. The application designed is used to control the temperature in a warehouse that stores explosives. The designed involves a temperature controlling circuit which acts as a feedback to the inverter to detelmine the speed selection of the motor according to the temperature range detected. Therefore the blower's (driven by the 3 phase induction Inotor) speed should vary according to the temperature changes.
