2.2 Data collection in large photovoltaic systems
Figure 2-8 Data collection in large photovoltaic systems
Data collection in large, extensive photovoltaic systems presents a challenge with regard to
the network technology. On the one hand, the reliable assignment of data and data security
must be implemented well; on the other hand, the hardware design needs to be inexpensive
and straightforward. This is particularly relevant in the special electrical environment of a
photovoltaic power station.
Although the PV generator generates a direct current in principle, the inverters in the system
likewise have an impact on the power cables. This means that in a photovoltaic system, the
inverter's method of operation generates AC voltage components on the DC side. This may
lead to inductive interference of cables and devices in the proximity of the generator’s DC
cabling. Depending on the inverter type and connection, the effect of these AC voltage com-
ponents can vary.
In order to avoid any influence on signals and data cables, corresponding standards regard-
ing the installation of data cables in the vicinity of power cables must be observed. Standard
DIN EN 50174 provides comprehensive directives on planning and installing communica-
tion cables in the vicinity of power cables.
