The containment in pig farming generates a large volume of effluent that can be treated by anaerobic digestion. To use the biogas generated in the process, in electricity generation, a better understanding of the variables involved is necessary. The objective of this study was the evaluation of biogas production parameters, power generation, performance of the generator group in the biogas conversion into electric energy and the avoided cost of electric energy of a pig farming property. Parameters of concentration, biogas production and consumption, and generation of electric energy were monitored, and the information generated was stored in a database. The results have indicated an average daily production of 443 m³, with an average of 0.10 m³ of biogas per pig and an average concentration of 68% methane. The average of electric energy generation was 324.5 kWh/day, and the efficiency of the generator was 17% with an average active power of 70 kW and a daily operation of 6.5 h. The avoided cost by self-consumption of electric energy generated in the property was R$ 13718.20, and during the monitoring period there was a total generation of electric energy of 70.5 MWh, of which 26.6 MWh were exported to the distribution network. The study also emphasizes that the appropriate choice of sensors and the methodology for monitoring and collecting data continuously could lead to an important data to use in correlated studies concerning generation of electricity from biogas.

养猪场中的安全壳会产生大量废水，可以通过厌氧消化进行处理。为了在发电过程中使用过程中产生的沼气，必须更好地理解所涉及的变量。这项研究的目的是评估沼气生产参数，发电量，发电机组在将沼气转化为电能方面的性能以及避免的养猪业电能成本。监测浓度，沼气生产和消耗以及电能产生的参数，并将产生的信息存储在数据库中。结果表明平均日产量为443  m ³，平均为0.10  m ³每头猪的沼气和甲烷的平均浓度为68％。平均发电量为324.5  kWh /天，发电机效率为17％，平均有功功率为70  kW，每天运行6.5  h。该物业产生的电能自耗可避免的成本为13718.20雷亚尔，在监控期间，发电总量为70.5  MWh，其中有26.6  MWh出口至配电网络。该研究还强调，传感器选用合适的以及监测和收集数据的方法不断地可能导致重要数据从有关沼气发电的相关研究使用。
