Problems solved by technology

Since the power is proportional to the square of the voltage, when the on-load voltage regulation gear of the transformer is adjusted, the power will change abruptly. This change will cause a certain impact on the grid. When the grid capacity is small, this impact will often exceed the allowable limit.

Abstract

The invention provides a submerged arc electric furnace power control method and device and electronic equipment. The method comprises the steps of obtaining a target power change curve and power adjustment parameters, wherein the power adjustment parameters comprise a resistance adjustment parameter and a voltage adjustment parameter; determining a current power formula with variable parameters according to the power adjustment parameters; determining parameters of the current power formula according to the minimum value of the difference between the target power change curve and the currentpower formula in a current adjustment time period; determining a resistance adjustment value and a voltage adjustment value in the current adjustment time period according to the parameters of the current power formula; and adjusting the power of the submerged arc furnace in the current time period according to the resistance adjustment value and the voltage adjustment value. According to the power control method for the submerged arc electric furnace, the optimal linkage of electrode lifting and voltage gear lifting is innovatively provided, smooth adjustment in the power rising and falling processes of the submerged arc electric furnace is achieved, and the problem that power jump type changes in the power adjusting process of the submerged arc electric furnace cause impact on a power grid can be solved.

Description

technical field [0001] The present disclosure relates to the technical field of electronic circuits, in particular, to a submerged arc electric furnace power control method, device and electronic equipment capable of realizing smooth regulation of submerged arc electric furnace power. Background technique [0002] The submerged arc furnace is an important smelting equipment. During the working process, the end of the electrode is buried in the material (referred to as the charge) in the electric furnace. The heating principle is to use the heat generated by the resistance of the charge when the current passes through the charge to melt the metal. [0003] The power of the electric furnace is determined by the two parameters of the electrode voltage and the electrode impedance. The electrode resistance can be changed by raising and lowering the electrode, or the electrode voltage can be changed by adjusting the on-load voltage regulating switch of the electric furnace transfor...
