The practical sessions form an important part of the seminar. For the thorough understanding of a technology and its applications it is essential to understand the technical basics. The easiest way of gaining this technical understanding is the haptic way – the way of working with the technology hands-on! We take the following approaches to the technologies:
In the technical exercises, we will use standard instruments to analyse the function of PV systems and do practical exercises on PV module configuration and electrical characteristics of modules, the effects of angles, orientation, shade and temperature on PV module performance, system planning, design, installation and simulation with standard software.
The RENAC Training Center houses several working solar thermal rigs. Students will use these rigs to become familiar with the systems and their components as well as to go through fault-finding and/or commissioning procedures. Students will also get the opportunity to work with solar thermal controllers and to perform system simulations with solar thermal software.
For the wind energy practicals, milliwatt-windtrainers are available. With this equipment, a variety of practical exercises will be performed, for example, measuring wind speed, measuring the power output of a wind turbine and how this depends on wind speed, demonstrating how the power output of the wind turbine depends on the number, position, shape and angle of the rotors, measuring characteristic curves of a wind turbine (current/voltage), plus charge and discharge of storage.
During the hydropower session the students work in groups to make a proposal for a small hydro development taking into consideration available resource and site conditions as well as environmental, planning and legal aspects. They look at turbine selection, energy yield and predicted income from the scheme.
The students will also be visiting a low head hydro site where see and learn about the intake, the screen cleaning system, the turbines and generators and the control system.
RENAC uses a set of model building components to demonstrate the various approaches to best practice in building design and construction. Furthermore, there are experimental rigs for industrial applications to allow students to perform a variety of exercises and become familiar with the latest energy saving methods and technologies in the commercial sector. We will have a closer look at ventilation and heating, building form and energy losses, timber framed and solid construction buildings, heat insulation of pipes, fittings and flanges, as well as compressed air with the possibility of locating leakages.
As for energy efficiency in industry and commerce, the following devices are available for examination in the training center: oil-free compressor with hybrid permanent magnet (HPM) motor, electronically controlled domestic circular pump, AC-fans and HPM motor and frequency converter. With these devices energy monitoring, energy efficient lighting and heat exchange will be demonstrated.
