摘　　要：功率因数补偿问题是正弦稳态电路功率分析中的难点。笔者结合多年的实验教学经验,在课堂教学中尝试了一种从电路实验入手分析功率因数补偿原理的教学方法。在揭示功率因数补偿本质的同时,帮助学生进一步深入理解平均功率、无功功率、视在功率及功率因数等相关概念。教学效果证明实验案例的引入对学生理解功率问题有较大的帮助。Power factor compensation is a nodus of sine steady-state circuit analysis. Based on the experimental teaching experience of many years the author presents a new method for teaching power factor compensation accord-ing to the experimental case,which not only reveals the nature of power factor compensation,but also helps students to understand further the corresponding concepts such as average power,reactive power,apparent power and power factor. The teaching result demonstrates that the introduction of experimental case is helpful for the students to understand the relevant power problems.
