Basics of Market Requirements
Substation Automation (SA) Systems with IEDs (intelligentelectronic devices) with serial communication have been now verywell accepted on the market (some 4000 systems worldwide)
Numerical devices with serial communication from different supplierscannot be combined in a system as in the old hardwired systemsbecause of a missing standard (only with an uneconomic effort)
The global, highly competitive market requests a standard for competitive performance
cost reduction
Both providers and utilities are global companies and requestsuch an integration or have to perform such integrations

Details of Market Requirements
The global market
needs a global standard
means a standard supporting all design & operation philosophies
Mixing of devices
at least like with copper cables
Cost reduction
by competition
by more intelligent functions
Cost reduction
for investments
operation and maintenance
Open, future-proof standard
for safe-guarding of investments
regarding suppliers and improving technology
for future extensions by bays or functions

Requirements for Standard in SA
Free configuration The standard shall support different philosophiesand allow a free allocation of functions e.g. it must
work equally well for centralized (RTU like) ordecentralized (SCS like) systems.
Interoperability The ability for IED’s from one or severalmanufacturer to exchange information and usethe information for the their own functions.
Long term stability The standard shall be future proof, i.e.
it must be able to follow the progress incommunication technology as well asevolving system requirements.
