The aim of this project is the design and implementation of an integral supervisory system for a PV plant. This system will not only monitor general parameters such as power or energy, but it will also delve deeply into detailed operation indicators. Weather Conditions (Wind, temperature, rain rate, humidity...) Production per PV module (DC current, Module temperature) Inverters' electrical parameters (voltage, current, harmonic, PQ ...)
Likewise, all the information will be collected and processed by a centralized applicacion which will have some of the following features:
Visualization and Control (SCADA)
Signal and events procressing
Measurements storage (Database and ftp server)
Thus, this project will allow us to analyze a real PV plant with different PV modules and inverters, and therefore, the detailed study of plant operation. This will provide a better comprehension of the system and it is the cornerstone in order to ensure the system reliability and subsequently decrease the operation costs.
