CyberSWIFT has had the opportunity to work on utility GIS projects in close association with the state and the central government.
What is RAPDRP?
The RAPDRP or Restructured-Accelerated Power Development and Reforms Programme was launched in 2008 by the Government of India as a central sector scheme for improving the urban power distribution sector in the country, the programme focuses on the actual demonstrable performance by the utilities.
RAPDRP Work Undertaken by CyberSWIFT CyberSWIFT has undertaken RAPDRP work based on the R-APDRP SRS document issued by the ministry of Power, Govt. of India. In this project CyberSWIFT used its GIS expertise for the following:
- Town boundary identification and mapping within the area of interest as per the physical ring fencing by the utility.
- Procurement of Geotiff satellite imagery having 1 and 2.5 meter resolution (Cartosat-I) resolution for Kolkata UA, and surrounding area (Kolkata town).
- Digitization of base layers from imagery only for all individual town areas (AOI) including transportation (road, railways, rivers, canals, and water bodies.)
- Collection of important landmarks (like important govt. offices, religious places, important road crossing, major transportation centers, major educational institutes etc.) through DGPS survey (sub meter accuracy) to update the base map.
WBSEB has initiated the project of Power GIS under the APDRP (Accelerated Power Development and Reform Programme) consisting of GIS mapping of electrical supply units in the state of West Bengal. The objective is to use GIS in the management of Electricity Distribution Facilities and consumer indexing. The project involved mapping of electrical entities, location of consumer data, identification of unauthorized connections in the distribution zone and the identification of anomaly between actual power consumed and billing received against each electrical entity to detect power theft.
In this project GIS was used as an effective tool for power management. Entire distribution network from Sub-Stations, HT Poles, Distribution Transformers, LT Poles and consumers were mapped with the help of GPS systems.
Base maps were developed using topographical maps. Base map included administrative boundary, roads, major water bodies, forest areas etc.
The state electricity had also undertaken the project for metering of every DTR, which would record units distributed through the transformer. The GIS application and consumer indexing exercise allowed the department to audit the billing database under the mentioned DTR and thus locate area specific revenue loss.
CyberSWIFT had also developed GIS application software for the State Electricity Board named “BIDYUT” which means Electricity. The software is installed at the lowest administrative offices called supply units. The application provides officers from these offices a complete picture of their administrative areas. The application helped in fault location, resource allocation during adding of new consumers, maintenance etc.
The application had an inbuilt energy audit module. It provided distribution losses because of individual transformers as well as for the entire supply unit.
The project involves a GIS-GPS based corridor survey for the stretch Mejia to Barjora along with detailed survey of Barjora Sub-station / Industrial area. The scope of work involves survey of proposed route alignment, overlaying the route alignment on the developed GIS map, accurate location of towers on the map and linking profile diagrams to the towers on the GIS map.
Entire area was surveyed with the help of Total Station and DGPS. IRS Cartosat 2.5 image was used.
