R-APDRP GIS IMPLEMENTATION OVERVIEW
The Government of India in 10th Plan started Accelerated Power
development and reforms program
for reforms in distribution with following objective :-
Reduction
of AT&C losses
Bring
about Commercial viability
Reduce
outages & interruptions
Increase
consumer satisfaction
Considering the need for continuity and to rein in the
losses of the utilities, need was felt to continue the initiative of APDRP in
11th plan as well. On review of the status
and benefits achieved of APDRP,it was felt that to have sustainable
distribution business, it is essential to give impetus to IT enabling of the
sector on an integrated platform. The IT platform shall assist in capturing and
validating the energy and revenue model to gather in a transparent manner with accuracy.
Considering the difficulties of domain expertise in IT
area of the utilities and the experiences the utilities had, it was considered necessary to prepare SRS
template, which shall provide the IT infrastructure for drawing the baseline data while
addressing the need of IT back bone in the area of distribution business
process to capture the benefits of the investments on sustainable basis.
The Govt. of India has proposed to continue R-APDRP
during the XI Plan with revised terms and conditions as a Central Sector
Scheme. The focus of the program shall be on actual, demonstrable performance
in terms of sustained loss reduction. Establishment of reliable and automated
systems for sustained collection of accurate base line data and the adoption of
Information Technology in the areas of energy accounting will be essential
before taking up the regular distribution strengthening projects.
IT
Overview
In
pursuit of IT implementation & complete computerization of its business
process. Basic components of the new
system are:
•Application
Software (ERP Solution) with
seamless integration of various modules such as Metering Billing Collection
(MBC), Customer services (CS), GIS based Customer Indexing & Asset
management (AM), Meter Data Acquisition, Plant Maintenance (PM), Energy Audit
etc.
•Data
Centre (DC) with
robust Data & Application Servers.
•MPLS
connectivity linking the DC with various work centers.
•Workstations with capable/
trained users.
GIS
Application includes
•Procurement of
Satellite Imagery from National Remote Sensing Agency, Hyderabad or another
agency.
•Preparation of Base
maps by digitizing satellite imagery
•GPS survey of
Electrical network to establish geo-coordinates.
•Plotting the
Electrical Network on base maps.
•Consumer Indexing:
Door to door survey of Customers, identifying their service connections,
matching with commercial records and collecting/ updating data of every
customer for linking them (poles, DTs, feeders & substations).
•Integration with
asset management & Network analysis tools for performing various
activities.
Why
GIS ?
- •GIS in Electric Utility primarily deals with mapping of all the Assets of Utility.
- The business process of Electric Utility is very complex.
- Dynamic Nature of Data.
- Energy Auditing not possible without proper indexing of Assets as well as Consumers to their source of Supply.
Importance
of GIS
•Mapping
of Sub transmission and Electrical Distribution Network.
•Creation
of Consumer Database & consumer indexing.
•Load
flow studies with use of Network Analysis Tools.
•Along
with Network Analysis Tools , GIS can be used for Load Flow studies for
rectifying imbalances in network and for Load Forecasting.
•GIS
becomes an effective tool in optimal design and choice of substation location,
demand-side management, future load assessment and load planning.
•
Based on inputs from GIS, which is regularly updated and monitored, a robust
MIS can be built for analyzing and reducing ATC losses, improved revenue
billing and collection and load demand/ supply analysis.
Components
of GIS
•GIS
Application
•Field
Survey
-Network Survey(HT and LT )
- Consumer Survey
•Asset
Painting
•Network
Analysis
•Updation
of Data
Description:-
GIS
Application:
•GIS
Application is being developed on state of the Art ArcGIS platform.
•Whole
GIS application can be divided into two parts:
- Desktop Application
- Web Application
•Desktop
Application is a license based.
•Web
applications is an integrated, single sign on application which is available to
end users
on internal network.
Field
Survey:
•Field
survey has two aspects:
i. Network Survey
ii. Consumer
Survey
•Network
Survey is done with the help of GIS equipment which includes Base station and
hand held GPS Rovers.
•Base
station is set up at a central location of the area (city or town) where survey
has to be done.
•Predetermined
parameters for all the assets are uploaded into the handheld GPS Rovers.
•Surveyors
walk along the HT and LT feeders and capture the spatial position of the Pole, transformer, Feeder and Sub-stations.
