When calculating the heat generation power of such a system, it is necessary to take into account the surface effect and the proximity effect in the steel pipe, which lead to a significant increase in its electrical resistance. The total resistance of a steel pipe of an induction-resistive heating system (IRH) was determined by analytically solving a magnetodynamic problem. The verification of the methodology for determining power was carried out using physical and mathematical simulation of the operation of the IRH system at various current loads. For physical simulation, an experimental facility was installed, which is a section of the IRH system. During the tests, the current was recorded and the temperatures of the conductor, cable surface, pipe, and environment were measured. Transient thermal processes implemented at the facility are described by the differential equation of nonstationary thermal conductivity in a one-dimensional axisymmetric formulation. The volumetric power of heat release is determined using the proposed methodology. A comparative analysis of the temperature dependences obtained using physical and numerical experiments indicates a fairly good agreement between the results.</p>","PeriodicalId":39312,"journal":{"name":"Russian Electrical Engineering","volume":"48 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139644838","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The introduction of digital technologies into the processes of control and management of power-supply systems will ensure an increase in the reliability and quality in these systems. The paper suggests the introduction of a decision support system (DSS) into the system for control over the load modes of cable units, which makes it possible to determine the optimal load modes for specific operation conditions based on the temperature restrictions. The DSS, which is based on mathematical models, helps to develop control actions to force a reduction in the load of some lines when permissible temperatures are possibly exceeded. The recommendations for reducing the load should take into account the range of possible working currents for each line, which depends on the customer category and technological capabilities. The optimal operation mode, for which the insulation temperatures are not higher than permissible values and a relative decrease in the power consumption is minimum, has been selected.</p>","PeriodicalId":39312,"journal":{"name":"Russian Electrical Engineering","volume":"6 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139649322","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
