The aim of this study is the behavior of the squirrel‐cage induction generator in distributed generation operating under real working conditions (presence of harmonics and voltage and current imbalance) connected directly to the distribution network. In this case, the primary machine has methane gas from pig farming as fuel. In distributed generation, there are technical, operational, quality, and safety problems (accidental supply to the distribution network by generators or distribution branches). In this work, the objective is to study the behavior of the squirrel‐cage induction generator in the distributed generation, while operating in real operating conditions (presence of harmonics and voltage and current imbalance). In this way, the induction generator operates in unbalanced non‐sinusoidal steady‐state condition and a technical feasibility analysis when the generator loses the distribution network and does not require an islanding monitoring system due to demagnetization that occurs in the induction generator. The experimental tests are in steady state and with the squirrel‐cage induction generator entering the island. Thus, the computer simulation was divided into two stages, first in the steady state and after the island analysis of the induction generator.

用猪甲烷气直接连接到配电网的感应发电机鼠笼的分析

这项研究的目的是在直接连接到配电网的实际工作条件（存在谐波以及电压和电流不平衡）下运行的鼠笼式感应发电机在分布式发电中的行为。在这种情况下，主机将养猪场的甲烷气用作燃料。在分布式发电中，存在技术，运营，质量和安全问题（发电机或配电分支机构向配电网络的意外供应）。在这项工作中，目标是研究在实际运行条件（存在谐波以及电压和电流不平衡）下运行的鼠笼式感应发电机在分布式发电中的行为。通过这种方式，感应发电机在不平衡的非正弦稳态条件下运行，并且当发电机失去配电网络并且由于感应发电机中发生的退磁而不需要孤岛监控系统时，将进行技术可行性分析。实验测试处于稳定状态，鼠笼式感应发电机进入孤岛。因此，计算机仿真分为两个阶段，第一阶段是稳态，第二阶段是感应发电机的孤岛分析。
