英文摘要: |
The author of this paper has designed the hardware and software systems of the power harmonic tester.The hardware system consists of a STM32 chip,current transformers,A/D cir-cuits and displays.In the software,FFT and phase difference correction method are used to measure and adjust the power harmonic parameters.Then,The test results of the signal harmon-ics generated by signal generator and Matlab simulation results are compared,which shows that this design can provide a high accuracy value of the frequency and amplitude of power harmonic. |
