Supervisory control and automatic failure detection in grid-connected photovoltaic systems

This paper is about a new online monitoring system for PV system operators based on the SCADA operational philosophy. The analysis module in the SCADA system manages the information using OLAP cubes, thus it allows improving the query of big data quantities and realize multidimensional analyses in an efficient way. For fail detection this paper proposes a procedure based on the comparison of the real measured production in the inverters regarding to the predicted production using others elements in the PV park.
