DFIG Principles Training System
8010-DGallery
Description
The DFIG Principles Training System combines a modular design approach with computer-based data acquisition and control to provide unrivaled training in the basic principles of the doubly-fed induction generator (DFIG) to students that already have a sound knowledge of three-phase ac power circuits, rotating machines, and motor drives. The system features the Four-Quadrant Dynamometer/Power Supply, Model 8960, and the Data Acquisition and Control Interface, Model 9063, two state-of-the-art USB peripherals that greatly enhance the learning experience of students.
Training begins with the Three-Phase Wound-Rotor Induction Machine course. This course familiarizes students with the fundamentals of the three-phase wound-rotor induction machine, which can be used as a doubly-fed induction motor as well as a doubly-fed induction generator. The course covers the operation of the machine both with a short-circuited rotor and with rotor resistance.
Students then continue with the Principles of Doubly-Fed Induction Generators (DFIG) course. This course covers in detail the main components as well as the operation of doubly-fed induction generators. It explains how and why DFIGs are commonly used in wind turbines designed for large-scale production of electricity. The course also allows students to experiment with an actual doubly-fed induction generator implemented with power electronics modules and a three-phase wound-rotor induction machine.
Features & Benefits
- The training system teaches the principles of doubly-fed induction generators (DFIGs), including the operation of three-phase wound-rotor induction machines, which are used to implement DFIGs.
- The course curriculum of the Electric Power Technology Training Program is highly flexible and allows a multitude of different customized training solutions.
- The courseware includes student manuals and instructor guides with all the theory required to perform the hands-on experiments.
- All workstations, modules, and components are sturdy and protected against electrical damage to ensure a prolonged service life in a demanding environment such as a training laboratory.
- The modular design approach of the training equipment allows a large variety of courses to be performed using a small number of modules, without unnecessary duplication of equipment.
- All electrical components can be interconnected without electric shock hazard since all live parts of the connection leads are concealed and insulated.
- All electrical symbols representing the components used in a laboratory exercise are clearly silk-screened on the front panel of the modules.
- The training system includes two highly versatile USB peripherals:
- Four-Quadrant Dynamometer/Power Supply, Model 8960-2. This module can be mechanically coupled to all rotating machines to operate as a prime mover or brake.
- Data Acquisition and Control Interface, Model 9063. This module gives access to a large variety of computer-based measuring instruments and is used to control the various dc power electronics devices necessary to DFIG operation. All functions are implemented via the LVDAC-EMS software.
- The training system also includes two highly versatile power electronics modules controlled using the Data Acquisition and Control Interface:
- IGBT Chopper/Inverter, Model 8837-B. This module is used to implement the three-phase PWM inverter for DFIG operation.
- Rectifier and Filtering Capacitors, Model 8842-A. This module is used to implement the three-phase rectifier for DFIG operation.
