ANALYTICAL REVIEW OF Q-ONE TECHNOLOGY FROM DANIELI AUTOMATION

Abstract

The authors of the article provide an analytical review of the Q-One system from Danieli Automation, which is designed to provide efficient power supply to the main electric steelmaking equipment (arc furnaces, ladle furnaces, etc.). This innovative system is gradually gaining popularity among the world’s leading steelmakers due to the implementation of the “clean power bus” concept in terms of maintaining a low voltage duty cycle and high power factor. In order to determine the strengths and weaknesses of the proposed technology, the article considers the “classical” method of power supply to steelmaking furnaces using furnace transformers and filter-compensating devices. The authors emphasise that with this method, electrical engineers struggle with the consequences of the problem of low power quality in the networks of metallurgical enterprises, while the Q-One system successfully “fights” with its source. That is why this paper discusses the structure and main elements of the technology proposed by Italian experts. In addition, based on the analysis of open sources of information, the authors form a fairly comprehensive list of Q-One’s advantages and disadvantages compared to the “classical” method of power supply for electric steelmaking equipment. The authors conclude the paper with a recommendation to critically evaluate the potential advantages for specific conditions of implementation of the Q-One system, especially at metallurgical enterprises in Ukraine.
