摘要
提出一种基于可编程逻辑器件(CPLD)的电力谐波分析仪,提高了谐波分析的精度及响应速度,同时大大精简了硬件电路,系统升级非常方便。文章给出了主要的设计过程和仿真波形。
A harmonic analyzer based on CPLD was stated. It improves capability and response. Meanwhile, it reduces hardware largely. Upgrading system will be easier. The main process of design was introduced in this paper.
