Abstract:
Electricity is the vital engine for growth, development and prosperity for the country. The per capita consumption of electricity is the symbol of status of living hood. In developing country like India where about 70% of population living in villages, the per capita consumption is very less as compared to developed country like USA. In India there are 95782 villages which are still un-electrified on dated 31-03-2010. Thus the quest to rapidly and firmly put the Indian economy on the course of economic development is technically, a function of adequate supply and distribution of electricity. As Ministry of Power set the goal of providing "Power for all by 2012", there is requirement to optimally develop the means for effective utilization of available local resources in rural area for electrification.
In this dissertation different configurations of distribution system have been studied. The single wire earth return (SWER) system was observe to be the best suitable for rural electrification of sparsely populated area. For the purpose of planning of distribution system the conductor size and transmission voltage have been selected. By SWER system there is a voltage regulation problem for this purpose we studied step voltage regulator to maintain the voltage within the permissible limit. The SWER system has been simulated in PSACD with step voltage regulator.
As a case study, the three villages namely Thumny, Sathkilo and Lapchi have been selected for village electrification. These villages are located in West Kameng district of Arunachal Pradesh. The proposed distribution network has been prepared for an isolated micro hydel project Jangtangpu near Thumny village. For development of this distribution system various alternatives have been compared. The SWER system has been observed to be cost effective so it is suggested for implementation. The cost estimation of these alternatives including SWER system on the basis of cost of system has been prepared on the basis of local standard schedules.
