RESTRUCTURED ACCELERATED POWER DEVELOPMENT AND REFORMS PROGRAMME
AMIT YADAV 51452734
INTRODUCTIONR-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 :

PROJECT SCHEME DIVIDED IN TWO PARTSPart – A: (Part A can be done by HCL R-APDRP TEAM)Consumer Indexing, Asset MappingGIS Mapping of the entire distribution networkAutomatic Meter Reading (AMR) on Distribution
Transformers & FeedersAutomatic 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 FencingEstablishment of IT enabled customer service centreEstablishment of the Base Line data System
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 BalancingHVDS (11kV)Installation of capacitor banks and mobile
service centre etc.
MAJOR CHALLENEGES AND ISSUESGround realitiesTimelineRing fencing(help to make GIS-based network mapping and
energy accounting)Energy auditTechnical challenges in R-APDRP implementation like CCC (customer care center) ,WSS (web self service)Enterprise security , data protection and business continuityNetwork analysisGIS (Geographical Information System)Data migrationSystem IntegrationLong term benefits

POWER SCENARIO AND ITS GENERATION IN INDIAThe electricity sector in India had an installed
capacity of 214.630 GW as of February 2013The 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
ENERGY RESOURCES
Conventional energy resources
Non Conventional energy resources
Capacity addition target of 78,700MW by 2012
Capacity addition target of 1,00,000MW by 2017
DEMANDThe 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
Electric Power TransmissionEnergy 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
POWER TRANSMISSION FLOW
General overview of Generation ,Transmission and Distribution
Problem FacedLOAD BALANCINGThere are several problem one of them is load
balancingThe transmission system should provides for base load and peak load capability, with safety and fault tolerance marginsBROWNOUTS AND BLACKOUTS Brownouts occur when the supply power drops below the demand. Blackouts occur when the supply fails completely
Load SheddingRolling 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.
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
POWER DISTRIBUTIONElectric 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
