Transmission and distribution networks are frequently being expanded and reinforced,often resulting in more complex networks.This is valid for
electrical transmission and distribution networks,
as well as for gas,oil,water,wastewater and district
heating grids.
The task of monitoring and controlling the energy
transportation in order to achieve an economical
operation control requires an ongoing penetration
of the grid down to the lowest levels.
The increasing availability requirements of energy
and its distribution and transportation also increases the demand of control systems.New and
improved communication possibilities with higher
transmission bandwidths and new transmission
media allow telecontrol technology to mange this.
Continually increasing capabilities of decentralized
control and closed-loop control solutions,based
on higher performance microcontroller technology,also allows more functions to run directly in the
station.This is valid not only for new remote stations,but also in stations which have to be upgraded due to a higher demand for information or
station that need to be modernized due to age
(retrofit).
In all cases,the telecontrol interface is the basic
functional package.
The adaptation of new Intelligent Electronic Devices (IED) and expansion with application functions based on Programmable Logic Controller
(PLC) solutions must also be possible.It is the task
of modern RTU's to provide the right solution to
these requirements.

The deregulation activities in the energy market,
especially the metering tasks,requires more online
information in order to control the energy flow
and energy consumption.Municipal utility com panies,responsible for the electrical,gas,water and
wastewater grids,are moving towards controlling
these networks in a more centralized fashion,i.e.in
one central control center utilizing only one con trol system.This requires the different telecontrol
communication links to be harmonized.
The process data object model has to be coordi nated between the different grid types.
The standardization of telecontrol protocols and
the increasing capabilities of communication net works makes this possible.
A new RTU must be able to support demands of
higher flexibility by adapting ANSI and IEC tele control protocol standards.The new RTU shall
have the capacity to be connected to new commu nication media and digital communication net works.
