The
overhead
power line security & protection system
are mainly used for
facilites of pubic utitlies, power plants, overhead power
lines and transformer substations. The O-SSP-System consists of 4
major elements:
-
control center hardware
-
control center software
-
communitcation between the substations and
controlcenter
- substation
equipment
Control
Center Hardware
The
control center hardware is separated into two major
components.
-
telecontrol interface which connects the
communication lines from the substations to the
computer system
- computer
system is a host-client structure with a
main area which is the presentation of the
surveillances cameras
Control
Center Software
The
main part of the software is the O-SSP software which
monitors the pictures of the surveillance cameras of the
substations and the presentation of the alarms enabling
further steps to protect the overhead power lines. Additional information
of the transformer substation data and control are additional features.
Additional software like state estimator, etc. can be offered.
Communication
The
communication is another important and difficult part of the
system because the substations are far from public areas. Thus
different communication systems must be inplemented such
as
-
radio
-
fiber optics
- satellite
Substation
Equipment
The
substation equipment consists of
-
day light camera
-
infra red camera
-
independend power supply
-
communication equipment
- PLC
