Induction Machines - Objective

This document is a training manual for the real-time simulator for electrical machines test bench developed by OPAL-RT.
It is specifically designed to study operation, testing and commissioning of induction machines. This manual provides numerous basic exercises to improve the understanding and mastering the induction machine fundamentals.

The interactive test bench, with a 16HP power rating, comprises a DC current machine coupled with a three-phase induction, wound rotor machine.
This versatile system has adjustable DC and AC power sources, programmable passive loads, fuse-controllable protection system contactors, measurement devices and oscilloscopes.

Its structure, based on low power electrical machines operating in a typically real power system topology, allows running multiple interactive exercises on both the induction and DC machines.
The versatility of its features means that it can be used for training, whether at college, or professional and university levels, and that new exercises can be developed as needed.

Just like in the lab, the interaction between the user and the virtual test bench installed in the simulator depends on the limits of the protection system features.
This forces the user to adopt good testing and implementation techniques, or risk being unable to successfully complete the experiment.
Thus, it is possible for the user to self-evaluate their experimental practices or for the trainer to plan real laboratory tests that will help them assess how well attendees are learning.

Users will learn to apply these techniques to simulators in the fields of power, driven load dynamics, and transient phenomena attenuation that are closer to real industry than traditional low power training systems.
Furthermore, if the protection system is disabled, it is also possible to research maximum performance or faults that would be harmful to real test benches.

The introduction to this manual describes the approach suggested for teaching the basic experiments for integrating an induction machine.
A description of the test bench with each machine’s rating plate and the various base configurations used according to the operating mode is described in Section 2.

Section 3 provides a detailed description of the panel of the simulator, which serves as the interface between the user and the virtual test bench. This part is a complete reference for all components on the simulator panel and can be referred to during experiments.
Sections 4 through 8 describe the protocols for 5 exercises on the induction machine.
