Remote Terminal Unit RTU560

The Application Requirements

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 companies,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 control system.This requires the different telecontrol communication links to be harmonized. The process data object model has to be coordinated between the different grid types

The standardization of telecontrol protocols and the increasing capabilities of communication networks makes this possible. A new RTU must be able to support demands of higher flexibility by adapting ANSI and IEC telecontrol protocol standards.The new RTU shall have the capacity to be connected to new communication media and digital communication networks.

The engineering work is an important cost factor that can be reduced by standardizing the process object model and ensuring that it supports stateof-the-art engineering tools.The engineering tool of the RTU must be able to perform the task of a single,stand-alone RTU,as well as be able to be integrated into an overall data engineering concept for a network control system. In addition to the basic functions,(i.e.data acquisition and control) modern telecontrol systems are required to provide a higher degree of functionality within the stations e.g.:

• High functional scope for telecontrol application functions

• Execute control and closed-loop applications using PLC capabilities
