Araz Energy, GE Digital Energy, Azerbaijan, SpainIEC 61850 has become the Standard to be used in Modern Substations due to the multiple advantages that it brings to the different stakeholders involved during substation lifecycle. There are many examples of substations using IEC 61850 IEDs (mostly protection relays) and many papers from several manufacturers and from different users at various locations have already discussed about the multiple advantages of using this Standard. This paper will show the experience of Araz Energy using a Process Bus Solution in four 110 KV (as retrofitted projects) Substations in Azerbaijan.
Araz Energy proposal to BEG (Baku Electric Grid that is locally called Baki Elektrik Shabakasi/ BES) was based on the Hard Fiber Process Bus system made by General Electric-Multilin (as part of General Electric Digital Energy). The use of the Process Bus System is key as it brings all the benefits of a Digital Substation and regular SAS (some vendors call it DCS for Substation Automation) and implies changes in the way a traditional substation is being designed, built, serviced and maintained. The experience described in this paper is based on the feedback gained and lessons learned from all perspectives in practice from four different substations where the same concept was applied. Since then the use of Digital Substations has become a landmark in the way Substations should be designed, operated & maintained.
