The topology shown in Fig. 1 consists of a 3-phase VSI rated at medium voltage acting as a main inverter bridge processing the bulk power whilst being connected in parallel to a CSI acting as an active filter to cancel out the switching current ripple produced by the VSI. The CSI is connected via a series capacitor which minimises the voltage stress to only a small fraction of the fundamental grid voltage via a control approach shown in the paper. Therefore, the added installed power of the CSI is less than 4% of the main inverter bridge which should account for a small added cost. As a result, the hybrid topology allows for optimal device utilization to achieve high output current quality with minimal device ratings and potentially improved efficiency. The control of the CSI is independent to the main inverter bridge which means that the auxiliary converter solution can be retrofitted to existing medium voltage installations for power quality improvement.","PeriodicalId":6508,"journal":{"name":"2014 16th European Conference on Power Electronics and Applications","volume":"10 1","pages":"1-10"},"PeriodicalIF":0.0,"publicationDate":"2014-09-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85296100","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}

Insulation health state monitoring can be done by evaluating the high frequency current response to voltage step excitation by the signal analyses of the current sensors, which are also used for the control of the machine. This reduces the costs and number of necessary system components. A change in the current response is, amongst others, correlated to a change through insulation degradation. The dominant influencing parameters of the high frequency current response of the machine are parasitic winding capacitances as well as insulation resistances, which are slowly changing over time if the insulation is deteriorated through different stresses, e.g. thermal or electrical. These slow changes can be monitored over long time period and give evidence if additional maintenance steps are required. Thus an unforeseeable outage of the traction drive system caused by damage of the machine can be prevented. Before the insulation state can be evaluated certain signal processing steps are necessary to increase the sensitivity. In this work the method of stimulation as well as detection of changes in the dominant parameters is verified on a 1.4MW induction machine.","PeriodicalId":6508,"journal":{"name":"2014 16th European Conference on Power Electronics and Applications","volume":"84 1","pages":"1-8"},"PeriodicalIF":0.0,"publicationDate":"2014-09-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83803366","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}
