Title:
METHOD AND APPARATUS FOR CONTROLLING POWER OF ELECTRIC FURNACE
Document Type and Number:
WIPO Patent Application WO/2017/143955
Kind Code:
A1
Abstract:
Disclosed are a method and apparatus for controlling power of an electric furnace. The method comprises: obtaining an operating frequency of a power grid; comparing the operating frequency of the power grid with a rated frequency to obtain a frequency deviation value of the power grid; obtaining a power deviation value of an electric furnace according to the frequency deviation value of the power grid; and raising or lowering electrodes according to the power deviation value of the electric furnace to adjust the power of the electric furnace. The present invention solves the technical problem in the related art of power system failure due to that load fluctuation goes beyond the tolerance of an isolated power grid since the impact of load changes on the power grid are not considered during power adjustment of an electric furnace.
