Abstract :

In Uttarakhand state, different hydrological projects are there which are generating about 4613.23 Million Unit electricity which is more enough to distribute among the existing population, so state is exporting electricity to other states which is a main source of income to the government of the state. The population of the Uttarakhand state is about 84.89 lakhs at present state has sufficient electricity to distribute among the existing population but in future scenario by seeing that population is increasing is an alarming rate and urban scrawl , this condition may not be possible. Use of modern technology is essential for the development in this sector. Remote sensing, Geographic Information System (GIS), Geographical Information System, or Geospatial Information System is an emerging tool in this new most important area. With the help of this technology different studies can be done like Load Flow Studies, Load Forecasting, Management Information System (MIS), Total energy accounting, Installation of capacitor banks & network reconfiguration and High Voltage Distribution System (HVDS) etc. In this direction, one case study has been conducted at USAC, Vasant Vihar phase 1 region of Dehradun district of Uttarakhand state. The main objective of the study is to create Power distribution system. High resolution satellite data has been taken and georeferenced it in appropriate scale. Building the database primarily involves conducting GPS survey of consumer households, connected electrical feeders and distribution transformers. Different thematic layers has been developed such as settlement layer, road map, LU/LC (Land use and Land cover) map, DEM (Digital Elevation Model), Aspect map, Slope map, location map of poles connected to Transformer and position of Transformers etc. With the help of connected houses to the poles, Load on transformer has been calculated and result shows that in which transformer load is more It plays a key role in determining technical loss, planning and optimization of distribution system. With periodic updating and monitoring, GIS mapping of the Electrical Network and Consumer database helps in improved load management, loss reduction, better revenue realization, asset and work management and possibly better consumer relationship
