| An important issue in the modern power and energy industry
is the monitoring and control of power distribution grids,
with the ultimate goal to provide
maximum power utilization. To ensure that power is transferred
to the proper areas, an RTU (Remote Terminal
Unit) is one of the most important pieces of equipment used
to monitor and control
power
distribution. In the past, communication with RTUs was handled
using RS-485 multi-drop networks, but
the current trend is towards adopting TCP/IP Ethernet networks.
This type of RTU system
allows engineers to
carry out two important tasks. One task is the remote detection
of possible power drains. Considering that power companies
are generally
responsible for the management of hundreds if not thousands
of miles of power lines, it is easy to see that the ability
to detect power
drains quickly provides an effective means of balancing
power generation and usage to help conserve energy.
Another
important
task
handled
by the RTU
network management system is the maintenance of redundant
operational sites containing system management hardware and
software. This can be achieved using a serial device server
with the UDP Server/Client function, and thanks to the ability
for multi-destination data transmission, this type of setup
naturally forms an
RTU redundant control system. |
