It is derived from the conventional single-switch nonisolated quasi-Z-source DC-DC converter. The new topology is within the transformer based class of the galvanically isolated impedance-source DC-DC converters, while existing topologies are solely within the coupled inductor based class. This simple solution features low cost, high efficiency and reliability that suits low power or low-voltage applications. Theoretical predictions were verified with simulation in PSIM and experimentally with a 200 W prototype. The topology is further improved using the combined energy transfer principle.","PeriodicalId":334135,"journal":{"name":"2015 IEEE 5th International Conference on Power Engineering, Energy and Electrical Drives (POWERENG)","volume":"67 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-09-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131379368","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}

A description of the battery pack and a previously developed battery management system with cell balancing is given. Here the battery management system plays a significant role since it provides information for the interface converter operation. The DC grid parameters and battery operational limits are used to extract the operational modes required for successful interface converter operation. The converter circuit and implementation is discussed. Additionally the control commands of the interface converter are considered since the converter is a part of a larger system with dedicated master control block that supervises the operation of all grid connected devices.","PeriodicalId":334135,"journal":{"name":"2015 IEEE 5th International Conference on Power Engineering, Energy and Electrical Drives (POWERENG)","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-09-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116314498","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}

One approach is to provide primary substations with full redundancy, and another is to ensure backup from adjacent primary substations. This paper details the methodology to implement this consideration in a distribution network planning algorithm that has been under development for several years at Aalto University. A case study on a 10 kV suburban network area is demonstrated, comparing the benefit of endowing a GIS primary substation with dual HV busbars rather than just a single busbar, versus forcing backup to be available from the adjacent primary substations.","PeriodicalId":334135,"journal":{"name":"2015 IEEE 5th International Conference on Power Engineering, Energy and Electrical Drives (POWERENG)","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-09-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126998030","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}

However, the distance measuring units operation during earth faults with the fault resistance is not always effective.

The analysis of the distance measuring unit operation by using the new and classical algorithms in the different earth fault regimes with different values of fault resistance is presented.

In this paper, different works on eccentricity fault diagnosis of induction machines with different types of supply have been reviewed.
