This document discusses the R-APDRP project which aims to reduce aggregate technical and commercial losses in the electricity distribution system from over 30% to less than 15% over 5 years. It does this through automation and integration of utility processes. Part A of the project, which can be handled by HCL, involves activities like consumer indexing, GIS mapping, metering infrastructure installation, and establishing a baseline data system. Major challenges of implementation include addressing ground realities, meeting timelines, and overcoming technical issues in systems like CCC and WSS. The document also provides background information on India's power scenario and the responsibilities of junior engineers.
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. 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

& energy input > 350 MU)
Feeder Segregation / Ring Fencing
Establishment of IT enabled customer service centre
Establishment of the Base Line data System
5. Part – B: It includes:

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. 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
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. 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
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. 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. 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. 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
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
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.)
