3. Philosophy of Substation Control System ▪ Conventional Control Full of copper hardwire Less communication



▪ Digital Control Substation Automation System (SAS) 61850-1



Digital Substation (DSS) 61850-2 Extensive use of IEC-61850 based communication Source: GE Grid Solutions, “Session 70 – Digital Control System,” APPS, Stafford 2018

4. Digital Substation: Evolution or Revolution? ▪ Substation = critical link Transmission, and Distribution.

Generation,



▪ Substations can be made smarter by adding sensors, monitoring, automation, and analysis systems. ▪ DSS completely changes how substation monitored and controlled. Source: https://www.tdworld.com/smart-utility/article/20958258/digital-substation-evolution-or-revolution

6. Technical Comparison Conventional: more hardwire and civil works uses static or 1st generation digital relays only capable for network management/switching



Digital: more fibre optics and programming uses IEC 61850-2 IEDs capable of asset performance management

7. Why Digital Substation? Advantages of DSS: ▪



Interoperability according to IEC 61850s



▪



Lower instrument transformer requirement



▪



Improved asset management, safety, and reliability



▪



Opportunity of controllable cyber security



▪



Software based testing



▪



Fewer human operators



Considerations of DSS:

▪



11 years experience (1st world DSS in 2009 by ABB)



▪



Would require regulation updates



▪



Needs of competency upgrade on O&M engineer www.pln.co.id

9. Existing and Potential Use of IEC-61850 in Indonesia ▪ Basic substation measurement and control (SOGI)



▪ Use of MMS in IEDs for automated disturbance reporting ▪ Redundant inter-substation trip using GOOSE



▪ CB Failure and non-cascaded protection on transformer using GOOSE
