摘要
随着电网中非线性器件的使用,电网中的谐波含量显著增加,同时国民生产和生活对电能质量的要求也越来越高。谐波监测是电能质量监测的主要组成部分,本文介绍了一种高精度电网谐波分析的装置,它采用了PC104总线规范,且在DSP处理器TMS320F206中,采用了FFT算法进行实时高精度电网谐波分析和功率计算。本文介绍了该装置的工作原理、软硬件实现等。
With more and more non-linear devices used in the grid,the contents of harmonics also increase,while the power quality has been required more strictly. Harmonic is an important part of the power quality indicator. This paper introduces a high performance grid harmonic analysis device,which is based on TMS320F206 DSP processor, adopts the PC104 bus specification.FFT algorithm is used to calculate the real-time grid harmonics and grid power factor.The paper demonstrates the design theory and the hardware and software implementation of the device.
