Design, implementation and validation of advanced measurements and communications within photovoltaic plants

Laburpena

Design and validation of a low cost integrated electronic system for the diagnosis and maintenance improvement of photovoltaic solar plants. The system is able to trace I-V curves for each solar module individually without disconnecting them from the plant, without interrupting the electric generation and with a minimum impact over the energy production. Moreover the I-V data obtained are evacuated from the module under test through a novel PLC communications system using the same power wires installed in the plant as physical support.The main novelty of this system is the implementation of a single cable ring shaped topology pushed to work in resonance compatible with the physical topology of the power cabling in the solar plant.
