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.

The disclosure provides a submerged arc electric furnace power control method, device and electronic equipment. The method includes: obtaining a target power change curve and power adjustment parameters, the power adjustment parameters including resistance adjustment parameters and voltage adjustment parameters; determining a current power formula with variable parameters according to the power adjustment parameters; according to the difference between the target power change curve and the current power formula The minimum value in the current adjustment period determines the parameters of the current power formula; determines the resistance adjustment value and voltage adjustment value in the current adjustment period according to the parameters of the current power formula; adjusts the internal adjustment value of the current adjustment period according to the resistance adjustment value and voltage adjustment value Arc furnace power. The power control method of the submerged arc electric furnace provided by the present disclosure realizes the smooth adjustment in the process of rising and falling of the power of the submerged arc electric furnace by innovatively proposing the optimal linkage of the electrode up and down and the voltage gear up and down, and can overcome the power adjustment process of the submerged arc electric furnace The problem of the sudden change of medium power and the impact on the power grid.
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...
