Description

On-Grid Photovoltaic Trainer

Model PV-EGRID/EV
Model PV-GRID/EV (computerized version)

The proposed system, which uses real components available on the market, allows the study and experimentation of the operation of a photovoltaic panel

Description:

System configuration: grid-connected
The system consists of:

A) Table top silicon cell photovoltaic (PV) panel

A.1) Solar radiation sensor (PV-GRID/EV only)
A.2) Temperature sensor (PV-GRID/EV only)

B) Table top control panel including:

B.1) Grid-Tie Inverter
B.2) Electric load (lamp)
B.3) Electric instrumentation for detecting the energy flows in the different branches of the circuit
B.4) PC data acquisition system (PV-GRID/EV only)

Operating principle:

  • If the user consumption is lower than the available energy from the photovoltaic panel, the excess power is fed to the grid
  • On the contrary, when consumption is higher than the available energy, the additionally required energy is supplied by the grid

Training Program:

  • Components of a grid connected solar system for electricity production
  • Effect of solar radiation on the panel output voltage
  • Effects of shading on a real solar installation
  • Photovoltaic panel energy conversion efficiency
  • Interconnection of solar energy to the public grid
  • Operation and efficiency of a DC/AC inverter
  • Connection to portable rheostat PRH-1 (optional item)

PC Data Acquisition (PV-GRID/EV)

  • All instruments and sensors, as described above, are connected in Modbus network.
  • A specific software (developed with LabView) is supplied to monitor the system parameters
  • Parameters displayed:
    – All DC / AC parameters
    – Photovoltaic panel incident solar radiation
    – Photovoltaic panel temperature

  • The software enables to:
    – Calculate solar energy conversion efficiency
    – Visualize the solar radiation incident on the panel surface and its temperature and the energy flows to and from photovoltaic panel, public grid and load
    – Save the exercises data for future analysis or project work
