Power Consumption Mode Investigation of a Transformer with Asymmetric Load under the Condition of Active Parts Temperature Change

Influence of emulsols type on energy-power consumption and surface contamination at DC01 steel cold rolling on the continuous four-stand mill

“…Electricity consumption during rolling depends not only on the type of emulsion used, but also on many factors: on the setting of inter-stand tension [1,16], the realized stress-strain state of the material [16,17], rheological properties of steels [18], efficiency of intermediate recrystallization annealing [19] and other methods of processing rolled steel [20], structural features of the rolling stock and its working and conductive elements [21], technological state and obsolescence of electrical equipment designs [22]. Indicators of power quality [23], which depends on the efficiency and stability of workshop converters and transformers [24], have a significant influence on the stability of the electrical equipment of heavy-loaded machines, and, as a rule, the controllability of rolling mills. However, when research is carried out on one piece of equipment under equal influence of all these conditions, it becomes obvious that the effect on electricity consumption depends only on the factor that changes, that is, the emulsol used.…”

Energy Efficiency Evaluation for Battery Energy Storage Stations Based on AHP-TOPSIS

“…Li et al [8] proposed a model for calculating the losses of distribution transformers, which has a certain guiding significance for reducing losses of distribution transformers. Reva et al [9] studied the effect of active device temperature on the loss of transformers when connected to asymmetric loads. Regarding the research on the energy loss of converters, Ko et al [10] proposed an optimized modulation strategy that can reduce switching losses.…”
