Nowadays such aircraft are created only for a small number of passengers and the power of their electric motors is negligible. However, all the concepts of large full electric aircraft imply the use of high temperature superconductor technologies. The most promising concept for high temperature superconducting electric machines with high specific parameters technically feasible in the near future is a fully superconducting synchronous electric machine with a nonmagnetic core. At the output power of more than 1 MW, the specific power is anticipated to exceed 10 kW/kg at 77 K. The fundamentals of theory and the analytical technique for calculating the basic parameters of a fully high temperature superconducting electric machine with an outer ferromagnetic screen have been developed. To refine the developed analytical method, the 1,5 kW prototype of the all-superconducting electric motor for hybrid distributed propulsion system was developed. It was shown that the analytical calculation provides sufficient accuracy in determining specific power and other basic parameters of fully superconducting electrical machine.","PeriodicalId":371743,"journal":{"name":"2019 International Conference on Electrotechnical Complexes and Systems (ICOECS)","volume":"64 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131279580","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}

As an object of the research was chosen the 242/20 kV, 400 MVA, five legged power transformer. The aim of investigation was to determinate the acceptable level of power transformer load capacity by the criterion of the above-limit value of windings temperature excess over ambient temperature. To obtain quantitative estimates of the temperature criterion, additional losses due to eddy currents arising under the influence of geomagnetically induced quasi-direct currents was preliminarily determined and additional main active power losses caused by an operating current increase due to a multiple increase in the magnetizing current. The values of the geomagnetically induced quasi-direct currents in quantitative estimates corresponds to the recorded results of those currents in electric power systems. It was shown that the greatest increase in additional power losses is observed in grounded high-voltage windings, and in low-voltage windings the additional losses increased insignificantly. The permissible levels of the overload capacity of 242/20 kV, 400 MVA power transformer was established for different values of the geomagnetically induced quasi-direct currents and the ambient temperature. It was shown that increasing of load capacity above the set values could lead the overheating of power transformer windings, followed by thermal degradation of the main insulation and an increased risk of internal short-circuits.","PeriodicalId":371743,"journal":{"name":"2019 International Conference on Electrotechnical Complexes and Systems (ICOECS)","volume":"2 5","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132801243","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}
