One of the main problems of such systems, located in isolated areas of difficult access, is the inverters. The mean time before failure of these equipments has been shown smaller than expected. In these applications the inverters should have the following features: expansion flexibility and robustness; high efficiency; and adequacy to operate in adverse environmental conditions. The results presented in this paper are related to inverter's development taking into account these requirements. The paper will present the mode of operation of the system, showing its robustness and viability for utilization of the inverters in standalone renewable energy systems.","PeriodicalId":183864,"journal":{"name":"2009 Brazilian Power Electronics Conference","volume":"4 3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-12-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128604832","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}

Because the generator leakage inductance and resistance information were required for this control method, the influence of the estimation errors for these parameters was also investigated.
