Metodologia para levantamento de cargas de secadores e silos aeradores na região da bacia do rio Santa Maria - RS

Abstract

The agricultural sector is important for technological development and prosperity in several regions of Brazil. No different, in regions of the State of Rio Grande do Sul, such activity is the economic driving force of several municipalities. The municipalities belonging to the Santa Maria River basin are economically dependent on irrigation agriculture for rice and soybean crops. The requirement of water for irrigation and electric energy for pumping crops and drying and storing grains leads to the delineation of action plans for hydraulic and energy use. In order to correct water availability problems, partnerships between the Federal and State Governments and users of the Santa Maria River made plans available to regulate the flow of water through dams (Jaguarí and Taquarembó) and irrigation channels. It is expected that with the regularization of the water flow in the Santa Maria River basin, the energy demand will increase, seen today inefficient for the various production chains, such as the drying and storage of grains. The electrical energy profile of the region has regions that are not served by medium voltage distribution, this region being an intermediate zone between the two main energy distributors in the State of Rio Grande do Sul (RGE and CEEE). In order to meet the current needs of lifting loads for dryers and silos, the present work used the methodology of Interconnected Decision Support System (SIAD) in order to form a database of electrical demand information, the current survey of the electrical load and future expansions by application of Distributed Generation, thus exploring the region's energy potential. With information on energy demand from silos and grain stores, it is possible to reach an answer on consumption levels and direction of energy efficiency actions.
