-

Single entry of data

Configuration data needs to be entered only onceAutomatic transfer of configuration data between different systems (e.g. from substation automation system to network control center)Reduces the risk of inconsistent configurations


Example Adding a New Bay to a Substation

The configuration of the substation automation system is extended with information concerning the new bayThe network control center can extract information required (e.g. single line diagram)

Example : Use of information from aCircuit Breaker

Local operation

Several network control centers

Power plant control system


Process data is available everywhere in the power automation system

No unnecessary data conversion required

Example –Asset management System

A central asset management can administrate all devices (devices status and nameplate, version control)

SW upgrade can be handled from one single point

Global access to devices

From one single point in the power automation network, it is possible to access all devices

This includes access to name plate information of the process equipment

Intelligence through new applications

The acquisition of as much process information as possible increases the controllability of the system

Distribution of preprocessed information according the requirements of the information users

New automation functions possible through seamless information exchange

ExamplesWide area protection: Distribution of phasor information

Wide area interlocking: Distribution of switchgear position information to adjacent bays

Applications of "peer-to-peer" communication

tripping of circuit breakers:short information that needs to be transmitted with a low probability of loss within a few millisecondstransmission of sampled values from instrumental transformers: high amount of data, to be transmitted within a few milliseconds, loss of data needs to be detected
