摘　　要：为提高电子电路类课程的教学质量,丰富教学内容,尝试将科研成果引入到实验教学环节的思路,启迪学生使用软件PSIM去分析和解决科研问题。针对普通电源系统经远端低频电力载波信号触发进入受控状态的安全威胁,提出有源滤波器的设计方案,并在对电力载波电路详细分析的基础上搭建出完整的滤波电路。仿真结果表明,设计的有源滤波器对电力载波信号电平的平均衰减幅度达到97. 33%,进一步的优化过程指出,通过级联同结构的滤波器能够实现进一步的衰减,这对提高电源系统防触发的安全性将具有重要的作用。In order to improve the teaching quality of electronic circuit courses and enrich the teaching content,this paper tries to introduce the scientific research project results into the experimental teaching link,and enlighten the students to use PSIM to solve the scientific research problems. In view of the security threat of the common power system which is triggered by the remote low-frequency power carrier signal and enters the controlled state,the design scheme of the active filter was proposed,and the complete filter circuit was built on the basis of detailed analysis of the power carrier module circuit. The simulation results show that the average attenuation range of the designed active filter to the power carrier signal level reaches 97. 33%,and further optimization process indicates that the filter with the same structure can achieve further attenuation,which will play an important role in improving the security of the power system against triggering.
