摘要
本文介绍了一种产生电力系统谐波信号的方法,可以方便快捷的产生包含任意次谐波的谐波信号,而且幅值和初相角都可以控制,优点是精度高,速度快,文中给出了理论波形和实测波形的对比。本方法不但能产生电力系统研究所需的各种谐波,而且,还能发出高达18．7MHz的正弦波(以每个周期发8点计算),可以供其它各种试验使用。
A kind of signal generator is introduced in this article. The device consists mainly of DSP and high-speed D/A. It can generate any times harmonic wave. It can change conveniencely amplitude and phase .Harmonic wave in the power system affect seriously the quality of electric power, so people regard harmonic wave seriously. The harmonic wave signal generated by this device can be extensiv ely used in the field of harmonic wave research and restraint.
