To provide proper torque production, knowledge of the rotor time constant is essential. Many adaptation schemes have been presented using different paradigms. In this paper a scheme for rotor time constant adaptation is applied, which uses the difference between the measured and the calculated reactive power to calculate a correcting factor for the rotor time constant. Measurements have shown that the main inductance which is crucial to the calculation of the reactive power depends both on the magnetizing current and on the quadrature current. The adaptation scheme is therefore modified to consider this effect, improving the accuracy of torque production.","PeriodicalId":416125,"journal":{"name":"2008 18th International Conference on Electrical Machines","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129115019","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}

Must be highlighted that this generator is driven by a steam turbine, and the whole system with regulators and the equivalent of the power authority system in the point of connection (PAC) are modeled in the ldquoATP - Alternative Transients Programrdquo. Technical questions studied here refer to steady-state voltage profile, voltage stability, voltage dip due to a balanced three-phase fault, load rejection, distribution line outage and the behavior of machine regulators facing the aforementioned contingencies.
