Such resulting voltage can feed other three-phase equipment, but its quality depends on the capacitor and load characteristics, as well as the single-phase input voltage. To the authors knowledge, rotary converter component selection is mostly empirical as there is no publicly available document to formally design these systems. To address this issue, this paper first presents an analytic expression to select the capacitance value to minimize voltage unbalance, while taking into account its effect on the quality of power under load variations and harmonic distortions from the voltage supply. Quick reference tables are also presented to design the rotary converter motor size and capacitor depending on the load demand and power factor, as well as taking into account the theoretical limit of voltage unbalance and resulting harmonic resonance characteristics.","PeriodicalId":448644,"journal":{"name":"2020 IEEE PES Transmission & Distribution Conference and Exhibition - Latin America (T&D LA)","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124760892","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 operation of the DT is correlated to the lifetime of the insulation, consisting of general guidelines of the paper and oil. The durability of the transformer insulation is related to thermal supportability and the equivalent aging factor. Thus, its lifetime depends on the burdens supported during operation since the temperature of the windings and the insulating oil is proportional to the power loading in the transformers. Usually, Power Utilities (PU) without any previous study wait for problems to happen first, and then make solutions. This paper proposes a study of a multicriteria analysis for decision making in DT management using the Analytic Hierarchy Process (AHP) method. The following decision-making criteria are adopted: a lifetime forecast and equivalent aging factor of the DTs, reliability indicators, the impact of proximity to load centers and the distance from the DTs to the feeder. Based on the AHP, the objective of this paper is to provide a ranking that supports the decision making of the replacement priority or even reallocation of the equipment.","PeriodicalId":448644,"journal":{"name":"2020 IEEE PES Transmission & Distribution Conference and Exhibition - Latin America (T&D LA)","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130678526","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 most difficult transition the MG can handle is the unintentional islanding. One of the problems existing in the unintentional MG islanding comes from the need to switch between inverters' control modes. The other one is that MG may operate islanded with loads external to the MG in a period of time. In order to show this problem, two simulations are performed in this paper. The first one shows that the time delay to switch inverters' control modes could lead to MG shutdown. The second one, using just one inverter control mode with no need to switch modes, shows better results with more proper conditions to maintain the operation continuity of the MG.","PeriodicalId":448644,"journal":{"name":"2020 IEEE PES Transmission & Distribution Conference and Exhibition - Latin America (T&D LA)","volume":"100 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132279138","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 results reveal that the software provides coherent generation estimates, with percentage differences of less than 5% when compared to the real system for the performed simulation.
