Methods which do not fail at zero fundamental frequency have to rely on non-fundamental effects of the motor. In the non fundamental wave model based mechanical sensorless control of AC machines the flux/rotor position can be estimated by evaluating the current response to voltage pulses. This current slope is modulated by all spatial saliencies in the machine. Sources of these saliencies can be various, for instance the saturation of the machine by the main flux, the slotting, or anisotropy, as well as inter-modulation effects. In this paper the separation of the saturation signal, the slotting signal, and the inter-modulation signal components in squirrel cage induction machines operating at low and zero frequency using artificial neural networks (ANN) has been experimentally implemented and measurement results are given to show the advantages of the application of the proposed technique at low and zero speed sensorless control even at high load levels.","PeriodicalId":416125,"journal":{"name":"2008 18th International Conference on Electrical Machines","volume":"33 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":"121746906","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}

They started investigations that identified several features of design and operation of machines with negative influence on the explosion risk. The implementation of risk analysis tables in product standards enabled manufacturers to recognize an explosion risk in advance as well as to define measures to minimize it. Additionally, rotor and stator type tests were required to prove that machines are not even able to ignite an explosive gas atmosphere inside of them. After performing these tests successfully manufacturers are sure that explosion protected machines provide a very high security level and that normal partial discharges on stator winding insulation systems do not cause an ignition of explosive gas atmospheres. Moreover, plant operators may now profit from the manufacturers knowledge to secure the safe operation of motors in hazardous areas due to gas.","PeriodicalId":416125,"journal":{"name":"2008 18th International Conference on Electrical Machines","volume":"101 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":"127674652","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}

Since a superconducting magnetic energy storage (SMES) unit with a self-commutated converter is capable of controlling both the active and reactive powers simultaneously and quickly, increasing attention has been focused recently on power system stabilization by SMES control. This paper proposes a SMES with the fuzzy gain scheduled supplementary controller associated with the automatic generation control (AGC) for the improvement of load frequency control (LFC). It is shown that SMES with the gain scheduled supplementary controller can perform a more effective primary frequency control for multi area power system. Simulation studies based on MATLAB are presented on a two-area power system after carrying out the necessary modeling exercise.","PeriodicalId":416125,"journal":{"name":"2008 18th International Conference on Electrical Machines","volume":"10 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":"126386744","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}
