Avaliação da eficiência energética em sistemas de irrigação mecanizados nas lavouras de arroz da fronteira oeste

Abstract

In the 2014/15 harvest, according to the IRGA data, west border of Rio Grande do Sul accounted for 58% of state production, planting about 112 million hectares, whereas 50.6% of this amount by uprisings with mechanical electrical engines, 19.4% of this area is irrigated by uprisings with mechanical diesel engines, and 30.0% irrigate naturally. Because of the complexity of these pumping systems, it is essential to find new techniques to get a better energy advantage, in order to reduce losses in the electrical system and achieve a considerable reduction in electricity bill. The high value of taxes, particularly in the reserved time is a constant concern to the producers. The electricity taxes increased by 40.2% from April 2014 to 163.0% in the same period related to 2015. There is the need for awareness by rice producers to show greater relevance to the implementation of projects focused on curbing electricity waste. From a detailed study of energy efficiency of the property of the producer Gilberto Pilecco, it defined how much and how energy was being used in pumping for irrigation of rice. It was put to a comparison test of a work already carried out by the company in such facilities APS energy engineering where the degree of effectiveness in the implementation of the measures. Thus, proposed alternatives to improve the facilities in order to achieve a greater reduction of wastage and costs, particularly in the matter to the operation of the facilities.
