Abstract
The article presents the successful practices of development of dispatching of electric facilities on the example of a number of industrial enterprises of mining and metallurgical complex, implemented through digital transformation. The main directions of improvement of system of dispatching of electric facilities of the enterprises taking into account successful practices on implementation of systems of management of energy resources are formulated. The results of the pilot project of building a dispatching control system at one of the zinc enterprises at the level of the Department – sulfuric acid shop-are described. Reduced downtime of process equipment by more than 25% has been achieved. According to the results of the study at a number of metallurgical enterprises of the current state of their dispatching control system and management of electric facilities, an algorithm for improving dispatching as a new step towards its digital transformation has been developed. The work on the algorithm is transformed into a pre-project study with the development of technical specifications for the implementation of the proposed technical solutions and is a preparation for the planning of a pilot local project at the unit level. The article provides recommendations for replacement of the power equipment of the substation with the digital transformation and justification for the development of system collapse based on the assessment of the sustainability of technocenosis. The paper presents an example of constructing elements of expert system for condition assessment of power equipment of substations, as well as significant technological equipment of enterprises on the basis of the indicative method enabling to generate data to predict equipment condition and control the cost of repairs and maintenance of equipment.
