  21. SIGNIFICANT MILESTONES • 1000MW IMPORT FROM WR ON 16/07/2001. HVDC CAPACITY FULLY UTILIZED. • 500MW BEING AVAILED FROM ER FROM MARCH 2002. HVDC CAPACITY FULLY UTILIZED. • IMPORT FROM NEIGHBOURING REGIONS - 5105MU DURING 2001-02 - COMPARED TO 3898MU DURING 2000-01 (ie. A RISE OF 31%). • AC BYPASS ARRANGMENT AT HVDC STATION, BHADRAVATI UTILISED FOR FAST RESTORATION DURING DISTURBANCE. • PEAK DEMAND MET 20063 MW DURING MARCH 2002 - COMPARED TO 19428 MW IN MARCH 2001.(ie. A RISE OF 3%).THE TOTAL CONSUMPTION DURING 2001-02 - 130821 MU - COMPARED TO 127524 MU DURING 2000-01(ie A RISE OF 3%). • DORMANT INTER STATE LINES BETWEEN ANDHRA PRADESH AND KARNATAKA i.e. 220KV GOOTY-BELLARY & SADEM-TANDUR MADE USE FROM 1st & 2nd MAY 2002 RESPECTIVELY. • ULDC CONTROL ROOM AT SRLDC FULLY FUNCTIONAL FROM 1st MARCH 2002. • SLDC’s OF KARNATAKA, KERALA & TAMIL NADU EXTENSIVELY USING ULDC SCHEME. TRIAL OPERATION IN PROGRESS IN ANDHRA PRADESH.

  22. PROBLEMS • LOW GRID FREQUENCY • LOW VOLTAGES • HEAVY MVAR DRAWALS • CAPACITOR INSTALLATION-BACKLOG • MEAGRE RELIEF FROM AUFR’S • RELUCTANCE - MANUAL LOAD SHEDDING • TRANSMISSION CONSTRAINTS • PROTECTION CO-ORDINATION • GRID • DEFENCELESS • VULNERABLE

  23. SOLUTION • MAINTAIN FREQ BETWEEN 49-50.5 HZ • ACCELERATE SHUNT CAPACITOR INSTALLATION • REINSTATE 2 STAGE UFR’S • PROTECTION CO-ORDINATION • AUGMENTATION OF TRANSMISSION • SCIENTIFIC SETTLEMENT SYSTEM-ABT • FREE GOVERNOR MODE • SELF HEALING MECHANISM • CONJUNCTION

  24. KARNATAKA ISSUES 1 400/220 KV 500MVA TRANSFORMER AT HOODY CONTINUOUSLY OVER LOADED - FREQUENT TRIPPING. - GRID DISTURBANCES/SEPARATIONS 2 INADEQUATE SHUNT COMPENSATION - EXTREME LOW VOLTAGE (300KV) AT BANGALORE - FREQUENT POWER SWINGS - RESTRICTION IN INTER REGIONAL ASSISTANCE 3 NO REDUNDANCY IN 220KV NETWORK – LINES FULLY LOADED. 4 OBSOLETE PROTECTIVE RELAYS – FREQUENT MALOPERATION. 5 MAJORITY EXISTING 220KV SUB-STATIONS WITHOUT BUS-BAR PROTECTION. 6 POOR MONSOON - DEPLETED HYDEL RESERVOIR. - PERPETUAL OVER DRAWAL AT LOW FREQUENCY.

  25. DISTURBANCES IN SOUTHERN REGION DURING 2002

  26. ALLOCATION OF SHARES IN MW

  27. PETITIONS • SRLDC FILED 10 PETITIONS AND 3 AFFIDAVITS WITH CERC ON MAINTENANCE OF GRID FREQUENCY. • KPTCL FILED WRIT PETITION IN THE HIGH COURT OF KARNATAKA AGAINST CERC ORDER DATED 14-02-2002. • HIGH COURT OF KARNATAKA IN ITS INTERIM ORDER DATED 22-03-2002 STAYED CERC ODRER 14.02.2002. • SRLDC FILED LATEST PETITION WITH CERC ON 03-05-2002 ON MAINTENANCE OF GRID FREQUENCY.
