摘　　要：功率因数是电气工程学理论中的重要物理量,也是电力系统重要的技术参数和经济指标,用户功率因数的高低直接影响电网的电能损耗和供电质量,"功率因数提高实验"是电气工程实践教学的重要内容。文章结合工程实际,给出了三种不同负载下的实验教学电路形式,并对各个实验的数据进行了详细对比和分析。将这三种实验应用于本科实验教学,不仅能加深学生对理论知识的理解,还能拓展其专业知识,为今后从事工程技术领域相关工作打下基础。Power factor is not only an important physical quantity in electrical engineering theory, but also an important technical parameter and economic index of power system. The power factor of users directly affects the power loss and power supply quality of the power grid. Based on the engineering practice, this paper presents three kinds of experimental teaching circuit forms under different loads and makes a detailed comparison and analysis of the experimental data. Applying these three kinds of experiments to undergraduate experimental teaching can not only deepen students’ understanding of theoretical knowledge, but also expand their professional knowledge, which will lay a foundation for their future work in the field of engineering technology.
