Festo Home Energy Production Training System

Part of the LabVolt series of training systems, the Home Energy Production Training System combines a flexible, modular design approach with computer-based data acquisition and control to provide unrivaled training in home energy production systems. The system features the Four-Quadrant Dynamometer/Power Supply, Model 8960-2, 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 following four courses:

• DC Power Circuits

• Lead-Acid Batteries

• Solar Power

• Introduction to Wind Power

A Modular Design Approach

The modular approach for designing the training program and lab equipment enables instructors to start building their electrical-energy laboratory with a basic package of courses and equipment and add new courses and equipment over time without needless duplication of equipment. All lab equipment consists of modules that can be inserted into a workstation. Module dimensions vary between two standard EMS sizes: full-size and half-size. Symbols and diagrams representing the electrical components in each module are clearly silk-screened on the front panel. Standard, color-coded safety banana jacks are used to provide access to the various components in each module

The below chart shows all courses in the Electric Power Technology Training Program. Blue boxes highlight courses included in the training system covered in the Home Energy Production Training System, while dark grey boxes, if any, highlight courses that can be optionally added to this training system.

  • Features and Benefits
  • Topics Covered
  • The training system teaches the principles of home energy production directly in the laboratory. To this end, students follow a complete curriculum that includes these topics:
    • An introduction to the fundamentals of electricity, beginning with dc power circuits.
    • Courses that cover the principles of electricity generation from renewable energy sources (solar power and wind power), as well as its subsequent storage in lead-acid batteries.
    • More advanced courses that cover different electrical concepts and necessary to home energy production, such as dc power electronics, single-phase ac power circuits, and high-frequency power transformers.
    • A comprehensive course covering in detail the production of energy at home from renewable resources.
  • 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 very sturdy 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 is used as a dc and ac power source. It can also be used as a battery charger/discharger, a solar panel emulator, and a wind emulator, all with a large variety of configurable parameters.
    • 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 home energy production. All functions are implemented via the LVDAC-EMS software.
  • The training system also includes three highly versatile power electronics modules controlled using the Data Acquisition and Control Interface:
    • Insulated DC-to-DC Converter, Model 8835. This module is used to implement a solar/wind power inverter with HF transformer topology.
    • IGBT Chopper/Inverter, Model 8837-B. This module is used to implement various types of choppers and inverters.
    • Rectifier and Filtering Capacitors, Model 8842-A. This module is used to implement various types of power diode rectifiers.
  • Software upgrades for LVDAC-EMS and firmware upgrades for the Four-Quadrant Dynamometer/Power Supply and Data Acquisition and Control Interface are available for download free of charge on the Festo Didactic website.
