Real-Time Simulation of Three Phase Induction Motor Using Raspberry Pi

Abstract

These days’ simulators are playing a crucial role in day to day life. In order to reduce the cost and effort, people are preferring simulation rather than going for hardware. But this normal simulations can’t give a good idea of the system behavior. For much better understanding of the system real time simulation is the only option. This comes under a special case of normal digital simulations. In this thesis topics like, what is real time simulation means and what are its requirements are explained in detail. Some of the daily life real-time simulation applications have also been illustrated in a detailed manner. By the advancements in software technologies many simulation tools are available in the market for real time simulation such as RT-lab, eFPGAsim, MATLAB/SIMULINK. These real time simulators bridges the gap between theoretical knowledge and practical knowledge. Thus these are very helpful for students and researchers to get practical experience with greater flexibility, without going for the costly and bulky physical equipment. The main objective of this project is to simulate a low cost real time simulator. In this project real time simulation has been done using Raspberry Pi kit as the hardware simulator and Python Language as Real-time simulation software. In this thesis capability of Raspberry pi and its interfacing with outer world has been discussed in detail. The reason for selecting python and its advantages are also explained in detail here.In this thesis, topics like how the model of the induction motor can be represented in differential equations is also discussed in detail. There are also discussions about the different numerical methods that can be used to solve these differential equations and the suitability of these methods to a particular application.
