In this paper, the superconducting magnetic energy storage-fault current limiter (SMES-FCL) with the common part of superconducting coil (SC) is presented to solve both problems. During normal operation, the control of SC is employed to alleviate the output power fluctuation of DFIG. During system faults, the SC acts as the fault current limiter to augment the FRT capability. The control scheme of inverter and DC-chopper using PI controllers are described. Simulation study confirms that the SMES-FCL yields the superior stabilizing effect over the individual SMES or FCL.","PeriodicalId":159493,"journal":{"name":"2015 IEEE International Conference on Applied Superconductivity and Electromagnetic Devices (ASEMD)","volume":"349 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122715378","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}

This paper introduces two different types of superconducting fault current limiters (SFCLs) to mitigate the short-circuit current and improve the VSC-HVDC system's transient performance. The two SFCLs are inductive and resistive, and will be respectively placed in series with the DC transmission line. From the theoretical analysis and simulation evaluation, both of the two SFCLs can contribute to suppress the DC fault current and compensate the DC-voltage sag. In view of their specific performance behaviors such as current-limiting ratio and mitigating voltage fluctuation, applying the resistive SFCL may play a better role than the inductive SFCL.","PeriodicalId":159493,"journal":{"name":"2015 IEEE International Conference on Applied Superconductivity and Electromagnetic Devices (ASEMD)","volume":"60 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130615957","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 electrical tree is a serious threat to SiR insulation and it will cause breakdown when reaches the ground. The high carrying capacity of superconducting cable makes the magnetic flux density up to hundreds of mT around the conductor. However, the effect of high magnetic flux density on electrical tree in SiR has not been researched. In this paper, the magnetic flux density ranged from 0 to 400 mT. The electrodes were typical needle-plate electrodes. The frequency of the applied AC voltage was 50 Hz. The growth process of electrical tree was recorded by a microscope system and the pictures were taken. The experiment result indicated that the high magnetic flux density changes the tree structure and affects the growth of tree length and width.","PeriodicalId":159493,"journal":{"name":"2015 IEEE International Conference on Applied Superconductivity and Electromagnetic Devices (ASEMD)","volume":"111 3S 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123901172","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}
