| 确定电力谐波测试仪的硬件系统和软件系统的设计方案，其中硬件系统包括 STM32芯片、电流互感器、A/D 电路、显示屏等器件；软件系统中，采用 FFT 和相位差校正法，对电力谐波参数进行测量并校正；将信号发生器产生的信号谐波测试结果和 Matlab 仿真结果对比。对比结果表明，此设计测量频率和幅值的准确度较高。 |
| 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. |
