R-APDRP (Restructured Accelerated Power Development And Reforms Programme)

  1. 1. AMIT YADAV 51452734
  2. 2. INTRODUCTION  R-APDRP is meant for collecting baseline data for total energy audit and accounting, through an integrated IT strategy across the distribution value chain.  The objective is to reduce the ATC (aggregate technical and commercial) losses from the current level of over 30 per cent to less than 15 per cent over next five years, by automating and integrating various utility processes like  Part A of R-APDRP should be done by HCL TEAM to provide IT support and training for deployment of this project.  Modules under Part-A of R-APRDP project are shown below :

  4. 4. PROJECT SCHEME DIVIDED IN TWO PARTS Part – A: (Part A can be done by HCL R-APDRP TEAM)  Consumer Indexing, Asset Mapping  GIS Mapping of the entire distribution network  Automatic Meter Reading (AMR) on Distribution Transformers & Feeders  Automatic Data Logging for all Distribution Transformers and Feeders  SCADA/DMS in big towns / cities (with population > 4 lakh & energy input > 350 MU)  Feeder Segregation / Ring Fencing  Establishment of IT enabled customer service centre  Establishment of the Base Line data System
  5. 5. Part – B: It includes:  Renovation, modernization and strengthening of 11 kV level Substations, Transformers/Transformer Centre  Re- conductoring of lines at 11 kV level and below  Load Bifurcation, Load Balancing  HVDS (11kV)  Installation of capacitor banks and mobile service centre etc.
  6. 6. MAJOR CHALLENEGES AND ISSUES  Ground realities  Timeline  Ring fencing(help to make GIS-based network mapping and energy accounting)  Energy audit  Technical challenges in R-APDRP implementation like CCC (customer care center) ,WSS (web self service)  Enterprise security , data protection and business continuity  Network analysis  GIS (Geographical Information System)  Data migration  System Integration  Long term benefits

  8. 8. POWER SCENARIO AND ITS GENERATION IN INDIA  The electricity sector in India had an installed capacity of 214.630 GW as of February 2013  The world fifth captive country has produced an extra 31.5 GW  Non Renewable Power Plants constitute 87.55% of the installed capacity  On other side renewable resources constitute of 12.45% of installed capacity
  9. 9. ENERGY RESOURCES Conventional energy resources Non Conventional energy resources
  10. 10. Capacity addition target of 78,700MW by 2012
  11. 11. Capacity addition target of 1,00,000MW by 2017
  12. 12. DEMAND  The present Peak Demand is about 1,15,000 MW and the Installed Capacity is 1,52,380 MW  Power generation mix is thermal (63%), hydro (25%), nuclear (9%) and renewables (9%)  The projected Peak Demand and the Installed Capacity  Requirement in next 15 years is
  13. 13. Electric Power Transmission  Energy is transmitted at step up high voltages (132 KV or above) to compensate energy losses in long distance transmission  Transmission networks use components such as power lines, cables, circuit breakers, switches and transformers  Transmission efficiency is hugely improved by devices that increase the voltage
  14. 14. POWER TRANSMISSION FLOW
  15. 15. General overview of Generation ,Transmission and Distribution
  16. 16. Problem Faced LOAD BALANCING  There are several problem one of them is load balancing  The transmission system should provides for base load and peak load capability, with safety and fault tolerance margins BROWNOUTS AND BLACKOUTS  Brownouts occur when the supply power drops below the demand.  Blackouts occur when the supply fails completely
  17. 17. Load Shedding  Rolling blackouts(also called load shedding) are used to distribute insufficient power when the demand for electricity exceeds the supply Transmission Substation A transmission substation decreases the voltage of incoming electricity, allowing it to connect from long distance high voltage transmission to local lower voltage distribution.
  18. 18. FACTORS ON WHICH POWER TRANSMISSION DEPENDS • Voltage=IR or I*p L/A where p is rho • The amount of power that can be send over the power lines is directly proportional on the length of power lines • We need more voltage with increase in length of transmission line • Other factors also have significant effect like cross sectional area of transmission line , with more cross sectional area we need lesser voltages
  19. 19. POWER DISTRIBUTION  Electric distribution substations transform power from transmission voltage to the lower voltage used for local distribution to homes and businesses  The voltage used is appropriate for the shorter distance and varies from 2,300 to about 35,000 volts depending on utility standard practice , distance and load to be served  Urban and suburban distribution is done with 3- phase systems to serve both residential, commercial, and industrial loads
  20. 20. Shows how Power will be distributed
  21. 21. Hierarchy in electric power corporation
  22. 22. JUNIOR ENGINEER RESPONSIBILTY  Test like commercial feasibility test  Handle operation and maintenance department  Distribution  Change of supply type like commercial , educational etc.  Load enhancement  Change transmission  Change of connection  Disconnection
  23. 23. TYPES OF DISCONNECTION
  24. 24. AT & C LOSS  AT & C is abbreviated for aggregated technical and commercial loss  AT&C= 1 – Na * Nc where Billing Efficiency (Na) = Total Units Sold Total Input Collection Efficiency(Nc) = Revenue Collected( Rs.) Amount Billed(Rs.)
