Desarrollo De Un Sistema De Monitoreo Industrial Para Un Sistema Solar Fotovoltaico De 100 kW Basado En Protocolo MODBUS

Abstract

An industrial monitoring system has been developed for a 100 kW solar photovoltaic system, which allows acquiring data such as AC and DC voltages and currents, total energy generated, irradiance, ambient temperature and solar panel temperature, based on the Modbus protocol. For this, we start with the analysis of the architectures and topologies that allow a better data acquisition with this protocol, and then implement the programming in the PLC Siemens S7 1200 and perform the corresponding tests and simulations to verify its operation. The above is verified in a web platform of the company ERCO Energía, which is managed by a different area, where graphically the data can be observed by hours, days and months. In this way, the document shows the procedure carried out together with evidence of the field implementation of the project.
