文中分析了傅立叶变换谐波分析法的缺点，提出一种离散微分跟踪器算法的谐波检测
方法。采用TMS320F28335浮点DSP处理器作为整个检测系统的CPU，完成信号采集、数据处理和串行通信等。Matlab软件进行模拟仿真的结果表明，离散微分跟踪器算法对电网的随机干扰信号具有良好的滤波效果，实现了高精度、高可靠性的谐波测量。
关键词：离散微分跟踪器；DSP；谐波检测
Research on Discrete Differential-Tracker Arithmetic Harmonic Detection
Wang Xiaolei Wu Birui Wu Bingxin (Zhongyuan University of Technology，ZhengZhou，China 450007) Abstract: Analysing the defects of fourier transform harmonic analysis, this paper brings forward a method of discrete differential-tracker arithmetic harmonic detection. It adopts TMS320F28335 (DSP) as the whole detection system’s CPU, to realize Signal Acquisition, data processing and serial communication. Matlab Simulink results shows that discrete differential-tracker arithmetic has good filtering effects to the power grid random disturbance signal, it realizes the harmonic measure high precision, high reliability.
Key Words: Discrete differential-tracker; DSP; Harmonic detection
