This study aimed to evaluate the system of electricity generation through the use of biogas from a swine production unit, located in the municipality of São Miguel do Iguaçu, taking into account aspects related to consumption of biogas generation electricity. A flow meter aiming at recording the flow of biogas was used, it was used GCP-22 is the control equipment and generator protection; data acquisition is also performed using energy analyzers. These analyzers record production / consumption in a time interval of 15 minutes. It was observed that the month of May had the highest consumption, reaching approximately 18 m³ of biogas. Evaluating the period, the total energy generated from bike generator set obtained an approximate value 110.3 MWh. The power consumption of the property was 55 MWh, and 16.8 MWh consumed in the distribution network. The surplus energy exported to the distribution network was approximately 72 MWh. The average generation for the period was 605.93 kWh. The average consumption of biogas generator set by bike was 49.3 Nm³.h.

Abstract. This paper consists on monitoring and analysis of the power quality of a distributed micro-generation connected in low voltage that use the biogas as primary source of power. The generation unit studied in this paper is a rural property dedicated to swine breeding (Colombari Farm). It is located in the city of São Miguel do Iguaçu, on the west region of Parana -Brazil and has a nominal power installed of 75 kVA that is connected to the Parana's Electrical Company (COPEL). The aspects of product quality according to Brazilian and International standards were considered to develop the analysis of power quality and the distributed generation performance comparative. As result, it is expected to acquire the power quality diagnosis and offers of solutions that could adequate the power quality of the generation unit. Also, contribute in the planning and programing of electrical action that compose the generation unit leading to an improvement of the system

A produção de energia através da biomassa pode contribuir significativamente, bem como para diminuir a emissão de carbono na atmosfera e também minimizar o problema de contaminação da água no caso dos resíduos de criação animal e resíduos sólidos municipais. Diante desta problemática, este trabalho teve como objetivo, monitorar a quantidade de dejetos produzidos por animal na granja (L/dia), e também a produção de biomassa da granja (m³/dia). As análises foram realizadas na Unidade Granja Colombari, localizada no município de São Miguel-PR, oeste do Paraná. Volume de controle foi realizado por meio de um sistema de medição volumétrica, a partir de caixa d’água instalada na saída dos efluentes dos galpões de alojamento de suínos. O período de coleta de dados situou-se entre os meses de dezembro de 2011 e junho de 2012. Durante esse período, o volume médio de dejetos medido, correspondente a 82 suínos, foi de aproximadamente 723 litros de dejetos/dia. Pode-se observar o aumento da produção dejetos nos meses de dezembro e janeiro, reflexo de maior consumo de água e consequente geração de dejetos.
