Mismatch originates from several factors such as non-uniform modules aging, shading, dust accumulation, faults in tracker systems and so on. Evaluation of mismatch level is a difficult task because it is necessary to take into account many factors: power configuration, geographical position, weather conditions, quality of measurements provided by dataloggers, etc. Moreover, since different criteria can be applied to calculate the percentage of mismatch, different results might be obtained for the same PV system leading in some cases to wrong conclusions. With the purpose of introducing some approaches for the assessment of mismatch losses in large PV fields, this paper presents a study carried out from data acquired in an existing 300 MW PV plant in Brazil in which an experimental 2.5 MW subfield was realized using 60 kW string inverters whose input stage has more DC/DC input converters. This particular power configuration allows the calculation of mismatch at string level as well as at array level at the DC side input of each string inverter. A multi-criteria approach has been implemented with the purpose to evaluate the coherency of results. A modelling strategy, based on an integrated state-space average model, has been exploited in order to get all the electrical quantities in case of faults, missing or wrong measurements.","PeriodicalId":207935,"journal":{"name":"2020 International Symposium on Power Electronics, Electrical Drives, Automation and Motion (SPEEDAM)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129045672","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 developed method was tested by designing of a three-phase induction motor (IM) with DCR for the rated power 5.5 kW by constant supply frequency 400 Hz, the obtained results were verified with the evaluation of motor characteristics from a 2D Finite Element Method (FEM) motor’s model. The designed DCR core sheet was compared with DCR core sheets used in industry by designing of an IM with the same stator and air gap.

The main BDFRG advantage over a conventional doubly-fed induction generator (DFIG) is the lack of slip-rings and brushes, hence the higher reliability, maintenance-free operation and lower cost. The desired active and reactive power variations are accomplished using a vector control scheme, which requires the rotor position and speed information in wind power applications with maximum wind energy extraction. Electro-mechanical shaft sensors, commonly used for this purpose, are prone to failures in harsh environments, like those encountered in off-shore wind turbines, and particularly with regular brush replacement intervals of DFIGs, making the BDFRG an attractive brushless alternative. The proposed controller design has been shown robust and capable of producing quality rotor angular position and velocity estimates by implementing an inverter-fed winding (secondary) current based MRAS. The realistic simulation results presented have proven the high accuracy and effectiveness of the estimation technique for different test scenarios of the BDFRG.","PeriodicalId":207935,"journal":{"name":"2020 International Symposium on Power Electronics, Electrical Drives, Automation and Motion (SPEEDAM)","volume":"106 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114320206","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}
