Novel time-frequency techniques have been applied to these transient quantities, in order to detect the characteristic evolutions of fault-related harmonic components. The detection of these patterns, which are usually specific for each type of fault, enables reliable diagnostic of the corresponding failures. In this context, most of the works hitherto developed have been based on analysis of currents. However, in some applications vibration measurements are also available. The goal of this work is to validate the applicability of this transient-based diagnosis framework to vibration measurements. A specific time-frequency decomposition tool, the Wigner-Ville Distribution, is proposed. Experimental results prove the ability of the approach to complement the information obtained from the current analysis.","PeriodicalId":6309,"journal":{"name":"2012 XXth International Conference on Electrical Machines","volume":"13 1","pages":"2517-2521"},"PeriodicalIF":0.0,"publicationDate":"2012-11-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75269697","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}

Simulation can be affected by many parameters, such as: The air gap size (the design air gap is always different from the operation air gap due to the thermal expansion) and its uniformity. In this paper, a sensitivity analysis taking into account the air gap length and the excitation current was performed. The sensitivity analysis based on finite element simulation results was performed on an existing large hydro generator of 122.6 MVA, 13.8 kV, 60 Hz, 60 poles with 504 slots, 120 rpm. The obtained results were compared to the certain measured parameters such as the air gap flux density, line current and magnetic core losses.","PeriodicalId":6309,"journal":{"name":"2012 XXth International Conference on Electrical Machines","volume":"7 1","pages":"328-332"},"PeriodicalIF":0.0,"publicationDate":"2012-11-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75292211","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 EERD transforms the kinetic energy due to vibrations, to electrical energy. The developed model is based on the governing magnetic field equation expressed in terms of magnetic vector potential solved using the nodal-based finite element method and then coupled to the electromagnetic and mechanical equations obtained after modelling a quarter of vehicle system. The coupling is carried out firstly through the magnetic force, and then by the modified flux distribution due to the moving part displacements simulated by the MacroElement method. The cycles of vibrations are transmitted to the device as vertical displacements. The obtained results represent principally, the induced electromotive force and the electrical power output.","PeriodicalId":6309,"journal":{"name":"2012 XXth International Conference on Electrical Machines","volume":"500 1","pages":"2716-2721"},"PeriodicalIF":0.0,"publicationDate":"2012-11-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75376961","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}

Many approaches over the years have used signal processing approaches at a high sampling rate (1 second typically) to evaluate the appliance load signature and subsequently used pattern recognition techniques for identification from a previously trained classifier(s). The proposed approach tries to identify the usage of high power consuming appliance(s) by using the aggregate power consumption at 10 minutes interval from the meter panel. The novelty of the approach lies in using a time series windowing approach which gives addition information about an aggregate power state. The usage of hour of the day as input to the systems also takes into account the temporal behavior of residential users. The usage of Multi-label classification approach for identification is also new for this domain. The model is tested over the IRISE data set and the results are encouraging. Due to its low sampling rate with time stamped aggregate power at 10 minutes scale as the only input from the user, the proposed approach is both practical and affordable.","PeriodicalId":6309,"journal":{"name":"2012 XXth International Conference on Electrical Machines","volume":"1 1","pages":"2098-2104"},"PeriodicalIF":0.0,"publicationDate":"2012-11-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75567103","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}
