摘要

本文介绍了一种基于电弧电流和电压谐波数据确定电弧炉控制系统开关点的方法。首先，获取电弧电流和相电压瞬时值的测量数据，用于计算电弧电压信号;进一步，通过傅立叶变换，确定了电弧电流和电弧电压的奇次谐波和偶次谐波的相对值。根据电弧电流和电弧电压的谐波组成数据，对结果值的分析为电模式控制系统主要的新熔化阶段轮廓的形成奠定了基础。

Method of Switching Point Determination for Control System of Electric Arc Furnace Based on Data about Harmonics of Arc Currents and Voltages

The article describes a method of switching point determination for the control system of an electric arc furnace, based on the data about harmonics of arc currents and voltages. Firstly, the measurement data about electric arc current and phase voltage instant values was gained for the calculation of the electric arc voltage signal. Further, the relative values of odd and even harmonics of electric arc current and electric arc voltage were determined through the Fourier transformation in the switching moments of the operating curve and furnace transformer step. The analysis of the resulting values allowed forming the basis for a principally new melting stage profile for the electric mode control system, based on the data about the harmonic composition of electric arc current and electric arc voltage.
