DESIGN AND DEVELOPMENT OF A VOLTAGE DIP COMPENSATOR FOR A TRANSFORMER USING A STEPPER MOTOR WITH DIGITAL CONTROLLER

The author is to design and develop a voltage dip compensator for a transformer
using a stepper motor with a digital controller. The main task is to provide a
mechanism for the mechanical switch of the tap changer to move. The mechanism
will require a precise movement that can be controlled digitally. This report is
prepared to present the design and implementation of the design for this project. In
the early part of the report, the author will enlighten readers to the background of the
project, the cause for needing such mechanism and the objectives of this project.
Then the author will give a literature review and theory for the components used in
the project. Here the theoretical result of the design is also presented. Results of
circuit simulation and hardware constructed will be analysed and discussed in the
next chapter. The constraints and overcoming the obstacle in completing this project
will also be described. The author will conclude this report with the results of the
design and knowledge gained throughout the completion of the project.
Recommendations to further improve the design are presented at the end of this
report.
