Изобретение относитс  к области электротехники и может быть применено дл  регулировани  электрического режима дуговых электропечей .The invention relates to the field of electrical engineering and can be applied to regulate the electric mode of electric arc furnaces.

Известен способ автоматического регулировани  дуговых электропечей путем коррекции задани  регул торов перемещени  электродов в зависимости от разницы заданного и фактического расхода электроэнергии в каждой из фаз за заданные промежутки времени. Однако независима  корректировка задани  регул торов каждой из фаз не устран ет характерной дл  дуговых электролечей асимметрии нагрузки фаз.There is a known method of automatic control of electric arc furnaces by correcting the setting of the electrode displacement regulators depending on the difference between the specified and actual electric power consumption in each of the phases for given periods of time. However, independent adjustment of the setting of the regulators of each phase does not eliminate the characteristic phase load asymmetry for arc electric furnaces.

Цель изобретени  - снижение асимметрии нагрузки фаз и повышение точности поддержани  заданной средней мощности.The purpose of the invention is to reduce the phase load asymmetry and improve the accuracy of maintaining a given average power.

Зто достигаетс  тем, что корректировку осуществл ют поочередно в каждой из фаз, причем первой корректируют «мертвую, а последней «дикую фазу. При корректировке «дикой фазы, на которую оказывают наи2This is achieved in that the adjustment is carried out alternately in each of the phases, the first being the "dead and the last" wild phases. When adjusting the "wild phase, which have the most

большее вли ние изменени  режима остальных фаз и котора , в свою очередь, мало вли ет на режим других фаз, компенсируютс  изменени  режима, вызванные произведенной ранее корректировкой остальных фаз. За счет этого и достигаетс  снижение асимметрии нагрузки по фазам и более точное поддержание средней мои ности.the greater effect of changing the mode of the remaining phases and which, in turn, has little effect on the mode of the other phases, the mode changes caused by the earlier adjustment of the remaining phases are compensated for. Due to this, a reduction in the asymmetry of the load in phases and a more accurate maintenance of the average mineness is achieved.
