  1. WELCOME HIS EXCELLENCY Mr. SAHBAN F. MAHJOOB Minister of Power GOVERNMENT OF IRAQ & The Delegation

  2. Indian Power Grid – its Evolution • Phenomenal expansion since Independence • Generation : 1349 MW 101,866 MW (in 1947) (in 2001) • Grid : Local grid – at the time of Independence. State Grids – emerged in 1960s. Regional Grids – in 1970s. Five Regional Grids – Northern, Western, Southern, Eastern & North-eastern National Grid – under progress.

  4. Indian Power Scenario – at a Glance Existing • Installed capacity - 101,866 MWCoal – 71% Hydro – 25% Nuclear & others – 4% • Peak demand Peak power - 78,000 MW Energy (average) - 1395 MU/day • Availability Peak power - 68,000 MW Energy (average) - 1288 MU/day • Shortage Peak power - 10,000 MW (12.8%) Energy - 107 MU/day (7.7%)

  5. Indian Power Scenario – at a Glance All figs. are in MW Region Peak Installed Peak Demand Capacity Surplus/Deficit Northern 21,000 27, 000 - 2,100 Western 25,000 30,800 - 4,500 Southern 20,400 24,800 - 2,600 Eastern 7,800 15,700 + 2,000 North-eastern 950 1,800 - 25 • Limited exchange of power between Regions ---Main Reasons: • Inadequate interconnectors, especially from Eastern Region • Lack of proper Commercial and administrative mechanisms

  7. Power Transfer Envisaged from ER and NER by 2012 Table

  8. NORTHERN REGIONAL POWER SYSTEMSalient features • Largest in geographical area amongst the five regions covering 30.7% of the area and 28% of the country’s population. • Maximum variation in weather conditions from severe cold to peak summer. • Large distances between generation centers and load centers and power is transmitted over long distances. • Availability of Hydro generation reduces drastically in winter months. • Largest number of constituents (8 states/UT’s, 3 Central Generating Companies, one Central Transmission Utility and Bhakra Beas Management Board).

  9. NORTHERN REGIONAL POWER SYSTEMSalient features • Establishment of the first super thermal power station (Singrauli STPS) and 400 kV transmission system in the country. • Establishment of the first High Voltage Direct Current (HVDC) long distance transmission system in the country (2x750 MW, + 500 kV Rihand-Dadri HVDC bipole). • First HVDC back-to-back interconnection with Western Region (2x250 MW back-to-back HVDC station at Vindhyachal). • First 400 kV Static Var Compensators (SVC’s) in the country (2x + 140 MVAR SVC at Kanpur). • Largest capacity of combined cycle gas power stations amongst the five regions (2480.47 MW) located along the 700 Kms. long Hazira-Bijaipur-Jagdishpur (HBJ) natural gas pipeline of GAIL.

  10. Grid Operation by POWERGRID • Earlier performed by personnel from Central Electricity Authority on the platform of REB • Transferred to POWERGRID in stages -SRLDC 1994 -ERLDC 1995 -WRLDC 1996 -NRLDC 1996 • Overall improvement in grid operation since takeover by POWERGRID

  11. Overall Improvements by POWERGRID • Better hydro-thermal mix through objective & rational Scheduling. • Better merit order operation enhancing the overall efficiency. • Effective use of transmission lines and enhanced utilisation of their capabilities, retaining stability margins. • Better commercial practices. • Improvement in grid parameters (e.g. voltage, frequency profiles). • Better utilization of Inter-regional links. • Infused the grid discipline. • Lower backing down of Power plants.

  12. Overall Improvements by POWERGRID • Optimum capacity utilisation • Better co-ordination among constituents. • Transparency in grid operation. • Documentation of Grid Code, Regional operating Procedures, Black Start Procedures etc. • Introduction of modern State-of-the-art technology in grid operation. • Better communication facilities • Introduction of modern SCADA & EMS scheme (ULDC)

  13. MODERNISATION OF POWER SYSTEM OPERATION ULDC SCHEMEs

  14. UNIFIED LOAD DESPATCH & COMMUNICATION (ULDC) SCHEMES POWERGRID IS IMPLEMENTING ULDC SCHEMES IN ALL THE FIVE REGIONS WITH STATE OF THE ART SCADA ENERGY MANAGEMENT SYSTEM AND DEDICATED COMMUNICATION SYSTEM

  15. OBJECTIVES • REAL TIME MONITORING & CONTROL OF POWER SYSTEM OPERATION • REAL TIME ENERGY MANAGEMENT SYSTEM • * OPERATION SCHEDULING • * POWER SYSTEM ANALYSIS • * OPTIMUM LOAD GENERATION BALANCE • DYNAMIC PLANNING FOR RELIABLE SYSTEM OPERATION • REAL TIME EVALUATION OF IMPACT OF POSSIBLE CONTINGENCIES ON THE SYSTEM • PREVENTIVE ACTION TO ENSURE SYSTEM STABILITY

  16. QUICK RESTORATION OFGRID IN CASE OF DISTURBANCE • COORDINATED CONTROL OF MVAR & LOAD FLOW TO MAINTAIN OPTIMUM VOLTAGE & FREQ. PROFILES • OPERATION OF SYSTEM AT IT’S FULL CAPACITY THROUGH CONTINUOUS CONTINGENCY ANALYSIS • EFFICIENT, RELIABLE & SECURED OPERATION OF GRID WITH ALL SYSTEM PARAMETERS & NETWORK CONDITIONS UPDATED EVERY 4 TO 15 SEC • REAL TIME ENVIRONMENT FOR TRAINING DESPATCHERS TO COPE WITH CONTINGENCIES
