基于PSCAD的锁相环参数设计及仿真教学

锁相环原理及参数设计涉及到电路、数学和自动控制等学科，比较抽象，学生理解起来较困难。本文介绍了课堂理论教学与仿真演示、仿真实验操作及习题、检查实验报告和习题情况的仿真教学方法，以及基于理论分析归纳的参数设计原则，再在PSCAD/EMTDC暂态仿真软件中搭建锁相环模型，并进行仿真验证。教学实践表明，该仿真教学方法有助于学生更好地掌握锁相环工作原理及其参数设计方法，能有效提高教学质量。

Design and Simulation Teaching of PLL Parameters Based on PSCAD

The principle and parameter design of phase-locked loop involve circuits, mathematics, automatic control and other disciplines, which are abstract and difficult for students to understand. This paper introduces the simulation teaching method of theory teaching in class and simulation demonstration, simulation experiment operation and exercises, check experiment report and exercises. Based on the parameter design principles concluded from theoretical analysis, the phase-locked loop model was built in the PSCAD/EMTDC transient simulation software, and the simulation verification was carried out. The teaching practice shows that the simulation teaching method can help students better grasp the working principle and parameter design method of PLL, and can effectively improve the teaching quality.
