  9. Southern Region Grid Complexities in Monitoring & Control Integrated Opn of Ten Power Utilities Inter-Regional Energy Transfer ≈5000MU (HVDC) Generators –Hydro, Thermal,Gas/IPP 412 nos. Transmission Network 400/220kV 37802 Ckm Installed Capacity ≈28500 MW 40,000 POINTS Active Power, Reactive Power, Voltage, Frequency, Transformer Tap Position, Circuit Breaker Position, Isolator Position etc. Transformation Capacity- 43545 MVA Transformers (220kV and above) 474 nos. Dynamic Grid Conditions PROJECT COST:Rs 6840 MILLION(1230 MILLION YUAN) COMPLETED SIX MONTHS AHEAD OF SCHEDULE

  10. COMPLEXITIES • 107,600 ANALOG POINTS • 14100 TELEMETERED ANALOG POINTS • 23500 TELEMETERED STATUS POINTS • 705,000 BYTES TRANSACTED EVERY 10 SECS • 302 RTU STATIONS • 2300 KMS OPTIC FIBRE LINKS • 35 MICROWAVE LINKS • 288 PLCC LINKS • MORE THAN 1800 VIDEO TRENDS • SINGLE NETWORK MODEL FOR ENTIRE GRID • TRANSPARENCY

  11. CAPABILITIES • 500,000 ANALOG POINTS • 500,000 STATUS POINTS • MORE THAN 1800 VIDEO TRENDS • CONTINOUS DATABASE RECORDING • REAL TIME NETWORK ANALYSIS EVERY 5 MIN • AUTOMATIC TRIGGER OF DISTURBANCE CASES • REDUNDANCY AT COMMUNICATION, HARDWARE AND SOFTWARE LEVELS • DESPATCHER TRAINING SIMULATOR-INTERFACED WITH REAL-TIME SYSTEM

  12. ULDC-THE EYES AND EARS OF THE SYSTEM OPERATOR • ALL CONSTITUENTS GET THE SAME DATA IN REAL TIME. • TRANSPARENCY. • SYNERGY IN OPERATION. • NO “PASSING THE BUCK” APPROACH. • QUANTUM LEAP IN VISIBILITY TO OPERATOR. • INCREASED CONFIDENCE. • FOCUS ON SECURITY AND ECONOMY. • INCRESED SCOPE FOR TRANSACTIONS WITH OTHER REGIONS SOME ULDC PICTURES

  13. ULDC-THE EYES AND EARS OF THE SYSTEM OPERATOR • PREMPTIVE, DYNAMIC “EARLY WARNING” SYSTEMS. • LOAD ANGLE. • ALARMS • CONTINGENCY ANALYSIS • GRID LESS VULNERABLE TO DISTURBANCES. • ANALYSIS OF GRID INCIDENTS – ACCURATE AND EASIER • RESTORATION AFTER PERTURBATION BECOMES MUCH FASTER.

  14. OPGW STRINGING

  15. AVAILABILTY BASED TARIFF

  16. AVAILABILITY BASED TARIFF A RATIONAL TARIFF STRUCTURE SCIENTIFIC SETTLEMENT SYSTEM

  17. WHAT IS AVAILABILITY TARIFF? • PAYMENT OF FIXED COST αPLANT AVAILABILITY. • VARIABLE COST α SCHEDULED GENERATION • DEVIATIONS ATTRACT A FREQUENCY LINKED CHARGE.(UI-UNSCHEDULED INTERCHANGE)
