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

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.

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

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
