Abstract

In most of Indian villages vocational literacy houses are run by NGO in community centres. These houses impart trainingin vocational trades to empower potential youth and provide them self/or wage employment. These houses need lightingand power sources to conduct vocational classes in centre. Although these houses are grid assisted and henceconventional grid powered inverters are kept as a standby to provide power supply in absence of grid failure. In theseinverters power is drawn as a primary source from grid source even for small load and battery gets its charge as long asgrid exists and thus lacks the sustainable feature under load shedding. In order to overcome the above constraint, a noveldesign of solar-grid powered inverter producing green electricity has been proposed as a primary source. The inverter hasbeen designed to work always on battery mode for a period as decided by fuzzy controller. This is supplementedconsistently by grid/or DG, as and when needed, under high load energy requirement. Thus the controller eliminate orminimizes the grid/DG dependability and at the same time reduces its connectivity with grid/DG to its maximum extend inan optimal way and thus provide 24 hour x 7 days power to these literacy houses. The PWM technology is used to chargethe battery as well as to produce supply usable AC power to load with less harmonics, obtained and stored in battery bankfrom PV module. The use of dual battery bank for storing the PV energy and delivery of energy to load simultaneously areunique features of solar powered inverter to maintain sustainability.
