  • 1. HEP - New Control Centers for Croatia’s Distribution Grid Project Realization, Transition Phase to Network Manager Boris Krstulja, Krunoslav Slivaric (HEP ODS), Zagreb Boris Njavro (Koncar), Zagreb
  • 2. CROATIAN DSO (HEP – ODS d.o.o.)
    • 21 distribution areas from 400.000 to 40.000 customers
    • Zagreb area 25% of consumption
    • 4 biggest areas (Zagreb, Rijeka, Split and Osijek) 50% of consumption
    • Total:
      • 2,3 mil customers,
      • 17 TWh of consumption
  • 3. PARTNERS IN PROJECT
    • HEP – ODS as Investor
    • KONČAR as Main Supplier
    • ABB Sweden as subsupplier for Network Manager SCADA/DMS system (Release 2.3)
    • HP Hardware equipment (Alpha and Proliant servers)
  • 4. OLD SCADA SYSTEMS
    • PDP 11/44 computers supplied and installed by Končar in 1980s
    • ADLP 80 (SINDAC) communication protocol
    • Mostly DS -8 family of RTUs produced in KONČAR
    • Only SCADA functions (PROZA D/R)
  • 5. PROJECT FOR NEW CENTERS
    • Long story started in 1994 and ended in 2004
    • Features:
      • SCADA with DMS functions for 110, 30(35) and 10(20) kV network
      • Protocol conversion ADLP and IEC 101 to IEC 104
      • ICCP connections
      • Uninterupted operation – paralel opeartion of old and new center

  • 7. CONFIGURATION
  • 8. IMPORT PROCEDURE
    • MDF files from PDP computers (ADLP 80 communication)
    • CSV files with process data and new ASDU and IOA information
    • Plausibility and uniqueness checks
    • Import to DE database
    Protocol Communication address ADLP 80 No. of comm. unit (1-9) RTU address (1-15) IEC 101 No. of serial port (1-9) Device link address (1-255) Protocol Default ASDU address in new system ADLP 80 No. of comm. unit * 100 + address of RTU (101-915) IEC 101 No. Of serial port * 1000 + link address of device (1001-9255)
  • 9. TESTING (SAT1 AND SAT2)
    • Communication (interoperability)
    • Functions (SCADA, NMS, ICCP)
