•

PLC distribution network, with the master PLC gateway or gateways at the

electrical substation (hosting the MV/LV transformer, the repeaters and the

slave PLC devices (CPE)). The slave devices connect to the master device and

are accessible via their IP addresses, which are in a private IP addressing plane

different from that of public IP addresses delivered to the community subscrib-

ers.

•

PLC injectors, which are used for connecting the PLC devices to the LV or MV

public electrical networks at the electrical substation or to a point of an electri-

cal pylon close to the final subscribers.

Since the configuration of all the devices for all the technologies cannot, of

course, be given, we merely indicate the main parameters to be configured for each

type of device of the distribution network infrastructure in Table 12.3.

GPS Position of Distribution Network Infrastructure PLC Devices

To optimize the supervision and the management of maintenance interventions on devices

of the electrical network, each device can be spotted with its GPS position. This GPS posi-

tion is also used for easily positioning the architecture components on a mapping available

in the NOC (Network Operation Center) supervision tools.

Some products are used for configuring this position for each device via the HTTP

interface of the distribution network master device, as illustrated by Figure 12.14.
