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
