{"title":"Approximate Circuit Representation of Voltage Unbalance Emission Due to Load Asymmetry in Three-Phase Power Systems","authors":"D. Bellan","doi":"10.1109/GEMCCON.2018.8628545","DOIUrl":"https://doi.org/10.1109/GEMCCON.2018.8628545","url":null,"abstract":"This work investigates from a circuit viewpoint the phenomenon of voltage unbalance emission due to load asymmetry in three-phase power systems. Voltage unbalance emission occurs whenever a power system shows a lack of structural symmetry between the three phases. In such a case, in fact, the transformation methods, such as the symmetrical component transformation, provide coupled modal circuits. As a result, in a practical three-phase three-wire power system, the positive-sequence circuit injects current into the negative-sequence circuit and therefore the load voltage shows a negative-sequence component due to modal circuits interaction. Since in many cases of practical interest the asymmetry level in a three-phase load can be regarded as a small perturbation with respect to the ideal symmetrical condition, in this paper a weak-coupling approach between sequence circuits is proposed. More specifically, load asymmetry is investigated, and analytical conditions for circuit weak-coupling are derived. In this case an approximate equivalent circuit for the estimation of voltage unbalance emission is derived. Analytical results are validated by means of numerical simulation of a radial power system with asymmetrical three-phase load.","PeriodicalId":394870,"journal":{"name":"2018 IEEE 4th Global Electromagnetic Compatibility Conference (GEMCCON)","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121976343","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}
