| 摘 要： | 对基于自适应理论的4种常用的谐波检测方法进行了系统地分析,通过理论分析和仿真讨论了这些方法的动态过程、时间滞后、计算量以及稳态精度等特性.仿真结果表明:4种检测方法无论电压是否畸变都能准确地检测出谐波量,但是在动态过程、时间滞后和计算量上区别较大.实际使用时应根据实际要求选择.

| Abstract: | This paper discusses four kinds of harmonic detection methods based on adaptive theory.The characteristics such as dynamic performance,time lag,calculation number and stable precision,have been listed by theoretical analysis and matlab simulation.The results show that whether source voltage is distortion or not,the methods based on adaptive theory can detect harmonic accurately,but the other three characteristics are different.The appropriate method should be choosen in practice. |
