Cigre B Doowon Technical College Korea 1 Q12. How does one assure that SAS specification developed in 2005 allows for future solutions taking advantage of the continued SAS evolution and functional consolidation? Ans.: It ’ s hard to assure the future advantage with 2005 specification. The spec. must be changed or up-dated step by step phase.

Cigre B Doowon Technical College Korea 2 Why step by step? Process level equipments and devices in substation are not digitalized yet. IEC standard still continues to grow(supplemented & matured). High level AI technology may be applied using many data & information in SAS. Networking communications between substations will become further essential for utilities. All above may be continued to change.
