Besides SCADA data communication, distribution control
centers have additional requirements. It might be necessary to
provide a telephony system for operational purpose or chan
nels for Renewable Energy (e.g. wind farms).
Since MV networks might be restricted to city areas or larger
rural areas, the network design needs to be adapted as per
actual requirements. Accordingly communication networks
providing L2 Ethernet switching or L3 IP routing might be
required. For installation in MV substations extended tempera
ture range and immunity against EMC/EMI is required.
Distances to be overcome are typically in the range of a few
kilometers.
Today’s In-plant applications require enhanced Ethernet
communication functionality. Various services such as CCTV,
public address or access control systems require communica
tion with a central server or operator console.
In-plant communication refers to applications dealing with
security of the infrastructure and recovery to normal operation
after an incident. Therefore high availability of the communica
tion network and high performance features are required.
Some of the In-Plant applications require significant band
width (e.g. CCTV), therefore a proper planning of the network
for the initial and future expansion is needed.
To allow supervision and historical analysis it is necessary to
synchronize end devices (e.g. cameras) from a central time
server.
