“…Рассмотрим ситуации, когда на исследуемом электросталеплавильном агрегате (ДСП или УКП) осуществляется модернизация систем автоматического управления электрическими режимами и перемещением электродов с заменой старого регулятора на новый или на существующем регуляторе выполняется изменение таблиц уставок импедансов вторичного электрического контура Z2REF, сопротивлений дуг RARC.REF, параметров нелинейных регуляторов и других вспомогательных блоков, а также корректируются профили плавок, определяющие сочетания ступеней печного трансформатора NTR, рабочей кривой NOC и ступени реактора NR (при наличии) [10,11]. Будем считать, что выполненные изменения направлены на достижение технического эффекта по снижению удельного расхода электроэнергии W УД .…”

The paper describes an improved method for estimating the technical effect after correction of electric modes in electric arc furnaces and ladle furnaces. The main indicators of efficiency for these types of equipment are specific power consump-tion and electrode wear. The study shows that after correction of electric modes in electric arc furnaces and ladle furnaces through parameterization of electric mode control system (or implementation of new control system), estimation of these parameters may be inaccurate. This is caused by the inapplicability of direct comparison of specific power consumption and electrode wear over separate time periods, due to the impact of different technological fac-tors. In contrast with existing methodology, the improved method takes into account the impact of technological factors with unequal values over separate time samples. The new method is based on statistical and correlation analysis of electri-cal and technological characteristics for pre-warranty and post-warranty periods. The most unfavourable period for achiev-ing the technical effect is determined on the basis of average values analysis. Further estimation of the technical effect is provided in relation to the most unfavourable conditions. The proposed method may be applied for a more precise assess-ment of the efficiency of electric arc furnaces and ladle furnaces after adaptation of parameters in electric mode control sys-tem or after the replacement of a control system.
