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.
