R-APDRP GIS IMPLEMENTATION OVERVIEW

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.
