The article provides the description of high- and low-voltage ASG developed computer-based models with automatic system of excitation control based on IGBT transistors ensuring the possibility of voltage amplitude and frequency adjustment. The studies were conducted in the MATLAB system using the Simulink and SimPowerSystems simulation packages. Modeling results indicate that the use of frequency deviation signal in the excitation system on rotor winding to control it, allows to reduce the frequency and voltage deviations occurring in independently operating ASG, in load connection and shedding modes, as well as during ASG energizing by self-synchronizing method. The comparison of synchronous generator with ASG when additional powerful load is connected in the system, indicates a wider stability range in the asynchronized turbogenerator.","PeriodicalId":230353,"journal":{"name":"2020 International Ural Conference on Electrical Power Engineering (UralCon)","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117165950","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}

Calculations of insulation relative to the ground in quarry distribution electric networks of mining companies in the Republic of Tajikistan have shown that the value of capacitance currents of single-phase earth fault lies within 0.1 A to 0.37 A and depends on development levels of the companies. The active insulation resistances of the network phases relative to the ground are in the range from 18 k k Ω to 112 k Ω, considering the change in the network quiescence coefficient. The network capacity relative to the ground is in the range from 0.09 µF to 0.34 µF.
