一种关于电弧炉调节器的新思路

A New Thought on the EAF Regualator

在电弧炉电极升降调节器中,通过对三相电流和电压瞬时值的检测,就可计算出系统的有功功率、无功功率和功率因数。瞬时功率理论为今后电极升降调节器理论的发展提供了新的理论基础。

It is introduced to apply principle of instantaneous power theory to improve performance in electric arc furnace electrode posi- tioning regulator. Through detection on three-phase current and instantaneous voltage, we can calculate active power, reactive power and power factors of the system. If its principle is applied in controlling system of regulator, it will supply a new method for AC electric arc furnace regulator.
