Consisting of a low frequency transformer and a fractionally rated power electronic converter, the hybrid transformer can be applied to ensure a high power quality by controlling voltage, current, active and reactive power dynamically. For the application in grids with conventional grid protection infrastructure, hybrid transformers have to withstand considerable overvoltage and -current stresses during voltage surges or grid short circuits. Since the semiconductors are less robust than low frequency transformers with respect to these stresses, the effects of possible fault scenarios and a protection concept are studied in this paper.","PeriodicalId":119358,"journal":{"name":"2016 18th European Conference on Power Electronics and Applications (EPE'16 ECCE Europe)","volume":"936 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116198414","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}

While LI batteries typically have higher energy density, lower internal resistance and longer lifetime than PbA batteries, the module cost of LI batteries are typically three to five times the cost of PbA batteries. The objective is to design a HESS that 1) is cost-competitive with a PbA single energy storage system (SESS) and 2) maintains most of the performance benefits of a lithium SESS. A modular HESS architecture with a bi-directional dc-dc converter and controller is proposed, and a power-mix algorithm with active inter-chemistry battery state-of-charge (SOC) balancing is presented, simulated, and verified experimentally. The batteries, converter and control algorithm are modeled in MATLAB, and the effects of total ESS energy, vehicle loading, depth-of-discharge (DOD), and speed are explored. The cost and performance of the HESS are assessed side-by-side with PbA and LI single energy storage system (SESS) configurations of comparable total energy, using expected vehicle range as the performance metric. The experimental HESS has a total projected cost midway between the SESS PbA cost and the SESS Li cost, while providing 17% range and 22.5% efficiency increase over the SESS PbA vehicle.","PeriodicalId":119358,"journal":{"name":"2016 18th European Conference on Power Electronics and Applications (EPE'16 ECCE Europe)","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114802717","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}

Normally, the dc cable is represented either by a small capacitance or by pi-sections, which implies that the frequency-dependent effects of the HVDC cable are neglected. One should be careful when using these cable models for high frequency simulations, especially for dc series offshore wind farm, whose topology forms a resonance circuit and consequently, accurate model of cable should be adopted to represent the transient characteristic of the HVDC transmission system in a proper way. This paper shows that the two most common lumped parameter types of DC cable model: small capacitance and pi-section model are unable to provide equivalent damping effect as the Wideband cable model or universal line model (ULM). The Wideband model is suitable for Electromagnet Transients (EMT) analysis while its distributed parameters make it impossible to be transferred into a state-space representation. This paper first introduces the topology of a DC series offshore wind farm. Then the resonance characteristic of the wind farm topology is analysed based on different cable models. Finally the offshore wind farm is simulated with these three types of cable models and controlled by modular multilevel converter (MMC).","PeriodicalId":119358,"journal":{"name":"2016 18th European Conference on Power Electronics and Applications (EPE'16 ECCE Europe)","volume":"77 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124082941","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}

Currently, the automotive norms and standards are defined based on the characteristics of the voltage source. The current technologies of batteries for automotive applications have voltage which depends on the load and the state-of charge. The aim of this paper is to provide better system performance by stabilizing the voltage without the need of redesigning any of the current components in the system. To show the added-value of the proposed electrical topology, loss estimation is developed and proved based on actual components measurements and design. The component and its modelling is then implemented in a global system simulation environment of the electric architecture to show how it contributes enhancing the performance of the system.","PeriodicalId":119358,"journal":{"name":"2016 18th European Conference on Power Electronics and Applications (EPE'16 ECCE Europe)","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127780590","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 FMEA results are used to prioritize, investigate and analyze important fault cases in semiconductors, dc bus capacitors and sensors. Possible reasons of each fault, appropriate fault detection methods, possible mitigation algorithms and some design improvements are shortly presented.
