The control of kitebased HAWE is widely covered in literature whereas its influence on the power electronic components of the drivetrain has not been investigated so far. In this paper, we present an electro-thermal loss model of the power electronic converters of a kite generator system (KGS). Junction temperatures and converter efficiency are simulated for an exemplary KGS load profile. The required component ratings are calculated with focus on the machine-side converter (MSC) which suffers from application-related stresses. Variable switching frequency and increase of generator pole-pair number are investigated to reduce the MSC power rating.","PeriodicalId":173647,"journal":{"name":"2019 Conference for Wind Power Drives (CWD)","volume":"134 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133864677","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}

This simulation method aims to calculate the change of the airgap width of the generator during operation with external loads. First the electromagnetic field calculation will be discussed, including the calculation of eccentricities caused by external loads. Subsequently the mechanical modelling approach is presented including the application of Maxwell stresses on the airgap surface. The paper presents calculation results of the airgap widths distribution under different external loads.","PeriodicalId":173647,"journal":{"name":"2019 Conference for Wind Power Drives (CWD)","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114313447","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}

This paper shows how the method of cooling the generator may contribute to a further reduction of the LCoE. In the past it was usual to use completely closed generators with air-to-air cooler or air-to-water cooler like it is standard in larger industrial motors. In a further development step, open aircooling uses the ambient air directly as primary coolant. While changing to an open aircooling several advantages help to reduce investment costs, but this approach also opens up risks, which have to be handled carefully.In this paper the advantages are listed and all important risks are addressed. For each risk adequate counter-measures are presented to mitigate or completely avoid these risks.","PeriodicalId":173647,"journal":{"name":"2019 Conference for Wind Power Drives (CWD)","volume":"47 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127452943","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}

PEGS can emulate an artificial medium voltage grid up to 36kV. One of the PEGS capabilities is to add artificial series impedance to the voltage source in fa-vor of changing the virtual short circuit power at the point of common coupling (PCC). In order to verify the test bench UVRT tests it is essential to show if PEGS is capable to emulate same grid behavior and characteristics as UVRT-Container. Later, a com-parison of the simulation results of the developed PEGS test to the UVRT-Container test is presented. In case of a two-phase fault emulated by UVRT-Container, the im-pedance seen by the faulted and un-faulted phases are changed during the fault due to additional short circuit impedance connected to the grid. The aim of this paper is to show that the PEGS can emulate the impedance for each phase during unsymmet-rical faults.","PeriodicalId":173647,"journal":{"name":"2019 Conference for Wind Power Drives (CWD)","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132700576","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}
