A micro-plant produces electrical energy using solar energy. This electricity can be used to supply isolated sites or be returned to a public distribution network. In the proposed bench, the energy produced will be stored in batteries and / or consumed.
The bench is taught to allow students to make different measurements at the level of each component.
- Analysis and study of industrial components (solar panel, inverter, converter)
- Study the performance of chain components.
- Take the energy balance
- Measurement of voltages and currents at various points in the circuit
- Highlighting of electrical laws
- The information (curves, synoptic, curve as a function of time) is continuously visible on a touch screen.
The micro-plant is made of robust industrial components.
- A 300W -24V photovoltaic solar panel with monocrystalline cells.
- A stainless steel tube frame mounted on casters, two of which are braked.
- An IP55 electrical cabinet containing the electronic components:
- A rectifier / battery charger with integrated display of parameters.
- A 24V / 230 V inverter with Bluetooth connection
- A network analyzer that provides Power, Intensity, voltage information to consumers.
- Three charging lamps of 40W each.
- Three measurement points accessible on the front panel:
- Voltage and current after the panel.
- Voltage and current after the rectifier.
- Current voltage after the inverter
- Two 12V 24Ah batteries
- A touch screen to display and save operating parameters.
- Differential circuit breakers, fuses
- On / off button
- Emergency stop button
- A user socket
- A USB socket
