Grid Topology in Carinthia Malta-Oberstufe Rennweg Zirknitz Innerfragant Außerfragant St. Leonhard Malta-Hauptstufe Treibach Gurk Reißeck Wolfsberg Lieserbrücke Wölla Radenthein Malta-Unterstufe Wietersdorf Kleinkirchheim Lienz Steinfeld St. Andrä Spittal/Drau St. Veit Brückl Windischbach Oberdrauburg Feldkirchen Kamering Obersielach Ettendorf Würmlach Landskron Klagenfurt Lassendorf Schwabeck Tröpolach Nord Ost Gummern Hermagor Forstsee Koralpe Völkermarkt Seebach Lavamünd Vorderberg Warmbad West Süd Edling Bleiburg Gailitz Siemens Rosegg Freibach Annabrücke Fürnitz St.Martin St.Margarethen Feistritz Ferlach 110-kV 220/380-kV Dr. Robert Schmaranz – Austria – Session 3 – Paper 0570

  4. Islanded Operation Malta-Oberstufe Rennweg Zirknitz Innerfragant Außerfragant St. Leonhard Malta-Hauptstufe Treibach Gurk Reißeck Wolfsberg Lieserbrücke Wölla Radenthein Malta-Unterstufe Wietersdorf Kleinkirchheim Lienz Steinfeld St. Andrä Spittal/Drau St. Veit Brückl Windischbach Oberdrauburg Feldkirchen Kamering Obersielach Ettendorf Würmlach Landskron Klagenfurt Lassendorf Schwabeck Tröpolach Nord Ost Gummern Hermagor Forstsee Koralpe Völkermarkt Seebach Lavamünd Vorderberg Warmbad West Süd Edling Bleiburg Gailitz Siemens Rosegg Freibach Annabrücke Fürnitz St.Martin St.Margarethen Feistritz Ferlach 110-kV 220/380-kV 110-kV islanded grid (length: 180 km) participating power plants Dr. Robert Schmaranz – Austria – Session 3 – Paper 0570

  5. real devices simulation model Dynamic Simulation Model Matlab - Simulink • Generators • Hydro governor • Excitation systems • Grid elements • Loads Dr. Robert Schmaranz – Austria – Session 3 – Paper 0570

  6. Evaluation • Measured vs. simulated • time courses • Optimization of the • simulation model • Implementation of • nonlinear behavior • Sufficient Accuracy Dr. Robert Schmaranz – Austria – Session 3 – Paper 0570

  7. Minimal Machine Configuration • Number of additional machines • Varying operating modes versus • Number of machines in frequency control mode Dr. Robert Schmaranz – Austria – Session 3 – Paper 0570

  8. CONCLUSION • Accurate representation of real conditions • Main stability parameters for grid restoration • Detecting source of low-frequency oscillations • Minimal machine configuration - two machines in frequency control mode necessary - maintenance planning • Optimization of the grid restoration plan Dr. Robert Schmaranz – Austria – Session 3 – Paper 0570
