  • 4. Power Generation
    • India has fifth largest power generation capacity in the world.
    • Installed capacity of 162 GW (about 4% of global power generation).
    • Per capita consumption 704 kWh (world average at 2300 kWh)
    • 11 th plan target of 1000 kWh per capita consumption requires additional 100 GW power generation by 2012.
  • 5. Power Transmission
    • The current installed transmission facility is only 13% of total installed capacity.
    • Ministry of power plans to establish integrated National Power Grid by 2012 with 200,000 MW power generation and 37,700 MW (additional 20,750 MW planned during 11 th plan) inter-regional power transfer capacity.
  • 6. Power Distribution
    • Transmission & Distribution losses stand at 33% substantially higher than global benchmarks.
    • Reforms have been undertaken through unbundling State Electricity Boards into separate power generation, transmission & distribution units.
    • Privatization of power distribution initiated through outright privatization or franchisee route.
  • 7. Power Distribution continued
    • While there has been slow and gradual improvement in metering, billing & collection efficiency, the current losses still pose a significant challenge for power distribution companies.
  • 8. Generation History
    • Full scale asset management & mapping
    • Predictive, preventive and routine maintenance management
    • Work order generation, activity scheduling.
    • Open system platform and database management
    • Enterprise-wise documentation management
    • Manual logging of Data
    • Huge Man power deployment.
    • Vast count of instruments and data.
    • Persons expertise required to run the machines.
  • 9. Generation History Cont….
    • Manual follow up for running equipment in sequence.
    • No automatic alarm generation in case of fault.
    • No analysis provision available in the case of fault.
    • Auto staring of stand by equipment in case of failure of one is not possible.
    • Remote monitoring and control not available.
  • 10. ABB Automation System in power Plant
  • 11. Gross Generation 2004-05 Hydro 84497 GWh Nuclear 16638 GWh Thermal and Wind 486031 GWh No. Villages electrified 498286 Length of Transmission & Distristribution lines 6497727 Circuit km. Per Capita consumption 606.2 kWh Loss-- Transmission, Distribution,  Transformation and Unaccounted energy 32.15%
  • 12. TRANSMISSION NETWORK
  • 13.  
  • 14.  
  • 15.  
  • 16. Transmission History
    • Analog meters need logging of data by persons.
    • Controlling of over drawl by utilities is not possible.
    • Lot of time is required to collect and summerise data for transmission lines running in 100’s of KM.
    • No Grid discipline.
    • Localised operation was possible.
    • Quality parameters( Voltage, frequency andPF) monitoring was missing
    • Non availability of monitoring system was one of the reason for not connecting different regional grids.
  • 17. SCADA SUPERVISORY CONTROL AND DATA ACQUISITION
    • Was introduced in 2002
  • 18.
    • As the name SCADA ( Supervisory Control and Data Acquisition) implies its functions are two fold:
    • Scans the monitored system, obtaining and deriving data about the state and operating behavior of devices
    • &
    • Provides the capability to send control signal out to those devices to modify their operation
  • 19. AVAILABILITY BASED TARIFF
    • Intra-state ABT is a techno-economic tool for bringing rational tariff structure for supply of electricity from State generators to the distribution Licensees.
    • It is a mechanism for enforcing discipline in the Grid.
  • 20. Benefits of Intra – State ABT
    • a) Benefits to the Power System
    • Brings about grid discipline by maintaining frequency in prescribed band (49.5 to 50.5 Hz).
    • Ensures optimum utilization of available generation capacities.
    • Enhances opportunities for Open access, and Trading of electricity.
    • Scope for encouraging competition among generators.
  • 21. SCHEDULING
    • Following processes of Scheduling has been automatized:
    • Declared Capacity (Input)
    • Entitlement Generation
    • Discom’s requirement (Input)
    • Open Access Transactions
    • Inter Discom Transfer (Output)
    • Drawl Schedule Generation
    • Injections Schedule Generation
    • Unrequisitioned surplus Generation
    • Schedule generation on the basis of generation back-down.
    • Printouts of the schedules on the intranet portal of SLDC.
    • Automatic uploading of schedules on SLDC website on the lines of WRLDC.
    • Automatic calculation of Inter-discom Transfer of surplus power.
  • 22. Distribution History
